I'm at a bit of a loss on what to do with one of my cats and looking for a bit of advice.
We have 2 cats, a dog, DS1 who is nearly 3 and DS2 who is 4 months. The animals get on reasonably well together, black cat can be a bit of a thug to grey cat but previously we seem to have managed this ok. Since DS2's birth things don't seem to be going so well. Grey cat is prone to episodes of stress cystitis (normally brought about by black cats thuggish antics). Black cat has stepped up her bulling and also appears to be pulling out her own fur. Most of the fur on her belly and inside back legs has gone and she's now pulling out the hair around the base of her tail. I'm thinking that this is probably stress related.
Any ideas on how to combat this? Unfortunately DS1 has a habit of shouting and chasing the cats (this is discouraged and punished) and I think this may be the main source of black kitty's stress. I'm worried that my only option is to rehome her, she's an RSPCA kitty so would need to go back there. I would feel like a terrible pet owner doing this but can't decide whether this would actually be the kindest thing to do.
