OK, mother is a cat hoarder and has a thousand cats, one of which is somewhere over 15 as far as far as we can tell. Might be as old as 17. She was an abandoned stray in the apartment complex mother lived in and came in from the cold, so to speak, 11 or 12 years ago and she'd already been there for years before that.
Anyway, this one has recently taken to urinating in various places, including mother's bed. I suspect that the reason is the younger cats (6 two-year olds) love to play what I call The Great Game, which is to stalk whoever is in the litter box and attack them as they leave. Plus the young ones seem to have taken it upon themselves to try and drive the old one out of the "pride" by treating her roughly at every opportunity. It's also possible that she has a urinary tract infection but we'll never know since she can't really be handled. You can rub her all day long and she loves it, but if she sees your hands she freaks so vets are out.
Mother wants to get a cage to put her in but that just feels wrong, so any ideas?
