I am slowly introducing two kittens to my resident cat. I've been using the scent-swapping technique, and recently have been leaving the kittens in Maisie's room in their box. She is becoming more confident around them, but still occassionally hisses at the box, or growls at it.
I am already using a Feliway diffuser and putting some rescue remedy in Maisie's water. I had heard that applying some felifriend to the new kittens could help too - has anyone done this? When I do finally let them meet out of the box I want the intro to go as well as possible!
Also, how serious is hissing v growling? She used to growl a lot when the first came, and now it's just the occassional hiss if the make a noise or move suddenly.
Thanks all in advance for your help.
