The then-wife of the celebrity zoologist jailed for raping, torturing and killing dogs has revealed the moment she found out about his “evil” abuse — and how he begged her to send him dog books even when he was behind bars.

Adam Britton’s now-ex Erin told Australian news show “60 Minutes” that she was out of town on a work team when she was told cops had stormed their home in Darwin.

She had “no idea why or what the crimes were” — until a lawyer told her that her husband was accused of raping and torturing 42 dogs, killing at least 39 of them.

“She told me that there were crimes of animal cruelty and, you know, obviously there was bestiality,” she recalled in her first interview about the horror crime.

“And when she told me bestiality my brain was, like, denial, ” Erin said.

“Hearing that information is the most awful thing you could ever hear about your partner. It was so shocking … I felt sick I couldn’t speak. I couldn’t think,” she said.

 “He is a psychopath … I cannot comprehend still how someone could be so depraved, so evil.”

Britton, who worked with David Attenborough on the BBC, was sentenced to 10 years in prison last month for the horrific abuse as well as possessing child pornography.

Erin has since divorced the British-born zoologist, but says he continued contacting her from behind bars to beg for books on dog domestication, breed history and behavior.

“He’s writing about this as if he can, sort of, continue his fantasies in his mind, and it makes me really angry,” Erin said, saying the “disturbing” request “messed” with her head.

“He doesn’t have any consciousness of what is right or wrong, I feel like I’ve lost so much of my life and I feel like I’ve been completely duped,” Erin said.

“He’s just destroyed my entire life.”

Britton, a senior research associate at Charles Darwin University, began his abuse in 2014 — and only stopped when he was arrested in April 2022 after authorities were sent a video he had shared online of himself committing the abuse.

He engaged in discussions with users on encrypted messaging services about bestiality, animal abuse, the acquisition of dogs, and methods for disposing of their bodies.

A search of Britton’s laptop also uncovered 15 files of child abuse material he had sourced online, including content involving toddlers being subjected to horrifying acts.
