Butter will always and furrever be my friend.

I have been talking to my co-worker Gudrun (3 cats, after one passed away last year). Gudrun says to her opinion it would be a classic case for Bach flowers (www.bachflower.com)

She has treated Lisa who used to beat up the others with these and it worked. If I understand her right then you must find the cause for Butter's behavior. Is it more in him or in Mimi because the Bach flowers you use depend on that.

She thinks very highly about this therapy and she is in general not the esoteric type. I however have no experience.

Of course it would be better if you found a vet who had experience with them.

Anyway I wanted to tell you about it.
