My bf and I recently brought home a new kitten. Our other cat doesn’t seem to be getting along with her though. She’s hissed at her and left the room when the kitten entered it. Any tips on how to help them get along? Our older cat has been fine around other older cat’s and she was once a mom herself so I don’t understand why she isn’t getting along with our kitten. This is the kittens first day here. Is it just a matter of time or do we have to do something specific to help them get along?
