Does anyone here have experience with introducing kittens to cats? We had two 8 year old cats. Sophie was put to sleep last week; cancer, lymphoma. My missus adopted two kittens, 12 weeks old. So far we've tried: - the cat and kittens eating on opposite sides of the door - placing the kittens in carriers and hoping Bogart (the 8year old) would sniff them. Not a chance - allowing the kittens to roam and hoping Bogart would slowly approach - allowing everyone to eat within close quarters Bogart hisses, but always seems to run away. Ideas, thoughts...?
