Well, we have an old calico cat about 18 years old, pretty darned old for a cat and I think it may be time to put her down and I was wanting to hear some of your experiences with this. Here's what's happening: she has severe arthritis in her hips and back legs and the vet says osteoporosis may be a factor too, as a result she walks sideways and has trouble getting up; she begs for food all the time, even immediately after she's been fed (dementia perhaps?), has lost about 3.5 pounds over the past year or so; she goes to the litter box but has trouble squatting and just hangs her butt off the edge of the box and pees on the puppy pads I keep down there. Also she has to go several times before she gets it all out. And she has terrible breath from her bad teeth (we feed her canned food). She pukes a lot more than she used to, not hairballs, just plain puke. Nasty puke. She still has a good appetite, is alert and her coat looks ok (although it used to look better). She doesn't pee in any odd places, either. She seems to know who we are still but it just seems that her poor old body is failing her. My wife and I are up in the air on this; I want to take her to the vet and do the deed, but my wife isn't sure. Thoughts? Suggestions? Thank you.
