Clover and Callie used to get along really well, but ever since Callie had her kittens five weeks ago, whenever the two of them are around each other, Clover starts growling and hissing and sometimes swatting at Callie, and I don't know why. Does it maybe have something to do with her having kittens? We've never had a cat have kittens before, and all of the other cats act the same around Callie, but Clover seems to act mean towards her now. I don't get it.
Any ideas?
