A 30-year-old man from Norfolk, who was arrested on suspicion of attempted murder, has been released on bail after being declared not fit for interview.
Police said the three-year-old boy from Cambridgeshire remains in Addenbrooke's Hospital in a critical but stable condition, following the incident at Johnson's of Old Hurst on Thursday.
Officers were called to the zoo at 1.24pm by the ambulance service to reports that a boy had suffered serious injuries.
The boy was pulled out by staff from the zoo and received medical treatment at the scene.
On Friday, Cambridgeshire Police said the man, who is not known to the toddler, had been "assessed as not being fit for interview".
Detective Inspector Verity McCann, from Cambridgeshire Police, said: "Our enquiries are ongoing as we continue to understand the circumstances surrounding this distressing incident.
"Our thoughts remain with the boy and his family, and specialist officers continue to support them through this difficult time."
The man has been bailed until 18 September.
Police said on Thursday the boy had sustained serious wounds during the "distressing" incident.
The zoo at Johnson's is home to more than 100 animals, including crocodiles, Bengal tigers, African lions, capybaras, meerkats and sloth bears, its website said.

The crocodiles are kept in a converted cattle barn, which has metal-fenced elevated walkways looking down on large pools of water surrounded by tropical vegetation.
In a statement released after the incident on Thursday, the zoo said: "Our thoughts and prayers are with the boy and his family following the incident that occurred today.
"Out of respect to the family, our Tropical House will remain closed until further notice."
Johnson's of Old Hurst is a family-run farming business that now features a butchers, a farm shop, tea room, steakhouse and zoo.
The crocodiles were initially kept to help dispose of waste meat from the butchery, but they went on to be the start of a zoo, according to a blog post from the zoo.
Convicted killers Mark Fellows, 45, Lee Newell, 57, and David Taylor, 64, stabbed Kyle Bevan to death at high-security HMP Wakefield in West Yorkshire last year before "tucking him up in bed" and leaving him to bleed out.
Bevan, 33, was serving a life sentence with a minimum tariff of 28 years for murdering his partner's two-year-old daughter, Lola James, in Haverfordwest, Pembrokeshire, in 2020.
Fellows and Newell were already serving whole life orders when they killed Bevan.
Judge Maura McGowan imposed "new and separate" whole life orders on both of them for Bevan's murder.
Taylor was given a whole life order for Bevan's death, on top of the offences he was on remand for at the time.
A jury found the trio guilty on Thursday of murdering Bevan.
CCTV showed the three defendants following Bevan into his cell on 4 November and emerging less than five minutes later in "a satisfied, job-done mood", prosecutors said.
Taylor was on remand for the murder of Alisha Apostoloff-Boyarin - a 24-year-old woman he was in a relationship with but had grown tired of - and attempting to murder a police officer in an interview room at another high-security jail.
Justice McGowan jailed Taylor for life with a minimum term of 20 years for Ms Apostoloff-Boyarin's murder.
She also handed him a 30-year sentence for the attempted murder of the police officer and imposed a whole life order for the death of Bevan, as it was a second offence of murder.
Taylor, who had recently been transferred to Wakefield, had boasted about his ability to make makeshift weapons "out of all sorts". Some had been found in a bottle of chilli sauce in his cell after Bevan's death.
Newell was given a whole life order in 2013 after he strangled a prisoner who murdered a child and left him in his bed - an incident with a "chilling similarity" to Bevan's death.
He was first jailed for murder in 1989 for strangling his neighbour when she refused to give him money.
Fellows, a hitman known as "the Wakefield Dexter", had committed two gangland murders and was given a whole life term in 2019.
He had applied to be transferred out of Wakefield before Bevan's killing because of his dissatisfaction with the prison.
Fellows was the only one of the trio to attend court in person on Friday, with Newell and Taylor joining by video link from prison.

On the day of his death, Bevan was seen on CCTV walking into his cell followed by the three defendants.
The trio left the cell less than five minutes later "as if nothing had happened".
They could be seen shaking hands and appearing to congratulate each other.
The court heard it is not known "who did what" inside the cells, but that Bevan was likely held by his arms while being stabbed 25 times with at least two weapons.
Newell had an injury to his hand, while Fellows could be seen rolling up his tracksuit bottoms after realising they had blood on them.
Jurors heard one weapon, made from a folded piece of metal from the back of a television, was found on the ground outside Bevan's cell with his blood on it.
However, the weapon that caused the fatal injury was never found.
The trial heard that, as Taylor was being transferred out of Wakefield, he shouted in the vicinity of Newell: "Nice working with you and the Iceman" - a nickname for Fellows.
Essex Police said the woman, 18, was taken to hospital after she was seriously injured in the Chalkwell Park area of Southend on 13 June. She died on Friday.
Officers were called to the area at about 12.30am after receiving reports a group of people had taken "unauthorised control" of a small articulated loading vehicle.
Police said an 18-year-old man from Westcliff and a 17-year-old boy from Leigh-on-Sea have been arrested on suspicion of causing serious injury by dangerous driving.
They are on bail until September.

Essex Police said it is aware "there were a large number of young people in the area at the time, and we believe some may have witnessed what happened" in an appeal for eyewitnesses.
Kyrees Sullivan, 16, and Harvey Evans, 15, died after the crash in the Ely area of the city on 22 May 2023.
Disorder then erupted following rumours that police had been pursuing the pair before the fatal incident.
The Independent Office for Police Conduct (IOPC) later found no indication of contact between a police vehicle and the e-bike immediately before the collision.
Cardiff Crown Court heard that crowds gathered near the scene following the deaths, and people became openly aggressive towards police as officers tried to expand the cordon.
In her sentencing remarks, the Recorder of Cardiff, Judge Tracey Lloyd-Clarke, said: "Very soon rumours began to spread about the cause of the crash, including rumours on social media, and the police were blamed."
She added: "The police officers at the scene were abused and threatened with violence.
"As the police were moving the crowd further back, some people in the crowd began throwing missiles at the police - bottles, bricks, stones, bits of plasterboard, and other items were thrown at the officers.
"The missile throwing continued for hours."
The court heard people filmed and live-streamed the escalating violence on social media, with cars being set alight and petrol bombs thrown.
During the riot, 31 officers and one member of the public were hurt, with injuries ranging from bruising to sprained limbs and concussions, and there was "substantial damage" to the community.
The riot continued until the crowd began to disperse at around midnight.
This week, Judge Lloyd-Clarke passed sentences for 30 defendants on 17, 18 and 19 June. They were:
Ashdon O'Dare, 28, of Ely, Cardiff - six years and six months imprisonment.

The IOPC also said that while CCTV showed a police van earlier driving behind the teenagers, it was about half a mile from the bike, on a different road, when the fatal crash happened.
However, the investigation concluded the officer who was driving the van has a gross misconduct case to answer over the accuracy of accounts he provided to colleagues.
IOPC investigators also concluded the officer has a case to answer in relation to his driving, and language he used regarding the boys at the crash scene. The IOPC said arrangements are being made for the misconduct hearing.
Waleed Saeed was sentenced at Snaresbrook Crown Court on Friday, after pleading guilty to charges relating to four victims, and being found guilty by a jury on charges relating to another, in March.
The Metropolitan Police said Saeed began offending in 2018 and targeted young men from South Asian and Muslim backgrounds, believing they would be less likely to contact police.
Detective Constable Peter Collington, who led the Met probe, said: "The pattern of offending we have uncovered is deeply disturbing and shows a level of deliberate manipulation and cruelty that has caused immense harm to innocent men, with two of them being just 15 and 17 at the time."
The force's investigation began in August 2024 following reports of a rape in a London park. The victim said he had exchanged messages with someone he believed to be a transgender woman.
He then received threatening messages from another account run by Saeed, who revealed his gender and threatened to release the images if he did not receive payment.
When the victim said he could not pay, Saeed demanded that they meet and over the course of the following weeks, coerced the victim into late-night meetings in a London park, where he sexually assaulted and raped him.
Police arrested Saeed in November 2024 after tracing online accounts back to the 31-year-old - and after seizing his devices, detectives found evidence linked to other victims.
They later undertook extensive crosschecks of older, unsolved cases and uncovered reports dating as far back as 2018.
On 2 March, Saeed pleaded guilty to charges including two counts of blackmail and two counts of making indecent photographs of a child.
Later in the same month, he was found guilty of:
🞗 Four counts of rape of a man aged 16 or over
🞗 One count of attempting to rape a man aged 16 or over
🞗 One count of causing a male to engage in penetrative sexual activity
🞗 One count of threatening to share a photograph or film of a person in an intimate state
🞗 One count of blackmail.

"We want to be absolutely clear that no one should ever have their sexuality exploited or weaponised against them in this way. You will be treated with compassion, sensitivity and absolute confidentiality.
"What has been done to you is wrong, and we will do everything in our power to support you."
