This is Joey from the DD colony about a month or so ago. We've noticed for a while that he's been looking skinny and dirty and doesn't seem to eat but the last few days we've seen blood coming out of his mouth (I won't post those photos) so realized we really needed to get him trapped and get him to a vet.
I just got off the phone with the vet and it's all bad news. Joey is in rough physical shape and has tumours in his mouth that are probably cancer. We decided the most humane thing for him is euthanasia so I'm afraid Joey has crossed the Rainbow Bridge. I didn't know this cat well but the death of any cat is very upsetting. I know that it was the right thing to do, at least he is no longer suffering and didn't have to die a painful death on the street.
