I'm very sad because my best friends husbands cats time has come to cross the rainbow bridge. He's very old, 19 years old, and is basically a one person cat, her husbands. He's been his therapy cat ever since they got him. My friends hubby is a Vietnam vet, has suffered from PTSD, and now has Parkinson's. I noticed the last time I was at their house he was walking very stiff. I suspect arthritis, among other things. He tried to jump out of his favorite chair, missed, hit the floor and had a sort of fit squealing and biting his tail, evidently in severe pain. Our vet, the one we both use, is out after having surgery., so my friends will have to contact his recommended replacement vet. To make things worse, my friends husband has to have back surgery on Monday. They plan to do the euthanasia on Tuesday. My friend is not particularly an animal person, but she is very upset about this. I told her this was far better than keeping him alive and having him die at home having such pain.. she has never had to go through this procedure so I told her a bit of what to expect, and urged her to bring Knucklehead back for burial. This never gets easier, even when the pet is not your own. I'm grieving for her, her husband and the hard decision they have to make.
