As title says really - I have a 16 week old kitten and a couple of weeks ago we adopted an 8 week old kitten (both female). We kept them separate for the first few days and have slowly introduced them to each other.
The older kitten started with a lot of hissing and growling and puffiness, that has now stopped but now when allowed in the same room she just makes a beeline for the little one, pins her down by the neck and bites her. She will let go when little kitten squeals but then repeatedly goes back to do it again until I split them up.
The little kitten doesn't seem overly bothered by this and in fact, cries for the other cat when she isn't there but it does all seem a bit savage.
So should I continue to separate them or do I let them get on with it as it's normal kitten behaviour?
Thanks in advance for any advice.
