Veterinarian Monica Tarantino rushed to help the kittens.
“They were in bad shape. I don’t think they would’ve made it, not through the rest of the day given the situation they were in. They were essentially going to suffocate,” Tarantino said.
It is not clear who left the kittens in the bag. They will need homes in about seven weeks.
Officials from the animal hospital said they did not need donations for the kittens but said that if people wanted to donate, they can give to their local animal shelter or animal rescue group in honor of the rescued kittens.
The animal hospital called police to investigate the incident.
