I used to have 3 cats, only had a crabby 14 year old tabby left when we got Ddog, when she arrived tabby boy very quickly informed her who was boss and she was always terrified of cats. He passed seat 3 years later and about 6 months after that we got 2 kittens. She was always scared of them too which was funny considering she was a very large dog, they always wanted to cuddle and play and she would give them side eye. We got another two cats and she would begrudgingly allow one to sleep next to her on my bed and they all kind of got along. She very sadly died last year.
Dcats range from 6 to 3 now. I would love another dog but is it fair on them to bring a crazy puppy into their home (they are all indoor cats), it could go two ways they may be like my old cat and wallop the puppy and put it in its place or more likely be terrified of it and hide away. Puppies are chaos and cats just love peace and quiet.
Another option would be another kitten (or two) and just be a crazy cat household (rescues of course) kittens as the others would accept them more easily. The last one got accepted straight away they were more interested in eating the kitten food.
I’m so torn, I’d love a dog I miss having a dog but I don’t want to upset my cats.
