We took in a stray, low and behold she had 3 kittens 2 weeks later! She is a sweet and loving cat and a good mom. The kittens are 3 wks old and I twice observed her biting them (different areas of their bodies) to the point they would cry. She will then start licking them and alternate between licking and biting. My vet (who I trust) suggesting separating them, in fear she may kill them. I want to do what's best for them.....please let me know if anyone has witnessed this with new moms. I have no experience with moms and kittens so I greatly appreciate any advice!
