Canadian who killed, ate the pig he adopted explains why

A Canadian man who killed and ate his recently adopted Vietnamese potbellied pig has explained why he chose to take her life.

CTV news reports in a now deleted Facebook post the man claimed the pig, known as Molly, began clashing with his dog and had slammed into a glass door shortly after her arrival in his home.

He apologised to outraged members of his local community, saying Molly was put down humanely.

"I do feel remorse and regret for my actions, and I would like to ask that people stop sending death threats to me and my partner," he wrote.

"If I could pay a fine to make people feel better I would, and I feel like the fact that I was not charged is where a lot of the anger is coming from."

Under Canadian law an animal can legally be killed by its owner so long as it is done humanely.

However that didn't prevent staff at the British Columbia SPCA getting upset when they found out Molly was killed less than a month after she was adopted on January 19.

Staff at the centre had spent nine months nursing the emaciated pig back to life after she was rescued during an animal cruelty investigation.

"I've been here 17 years, this is the first time I've ever heard of this happening," BC SPCA spokesperson Lorie Chortyk said.

Ms Chortyk says Molly's adoptive family have been banned for life from adopting any other animals, after breaking their "not legally binding" agreement to not kill the animal.
