We recently lost our dog to cancer. Keep; in mind that our cat, Mr. Stubbs has lost 4 friends in 3 years to old age or illness. The same day we had to take our latest dog to her final trip to the vet's, he has decided to start attacking our youngest cat(3yrs old) quite viciously. Mr. Stubbs is 13. Watson is 3. We got Stubbs at 6 wks old. He would curl up with our husky, Freya to sleep. We lost her 3 yrs ago. Then Sally(another husky), 2yrs ago. He then slept with a cat, Spunky. We lost him to old age not quite 2 yrs ago. He turned to Mia, our Staffie. We lost her to cancer last week. Now, he is continually attacking our 3yr old cat(got him at 6wks). The looks he gives Watson are evil. I'm sorry-that's the only way to describe it. He is very nasty. Prior to this, he was neurotic and paranoid, but not vicious. This has now changed. I'm at my wits end. Do you think this will pass? I don't want to have to find him a new home. I think it would damage him greatly to do that. Any suggestions?
