A friend of mine had a litter of day-old kittens (along with their mother thankfully) dumped on her farm over the summer. We already had 3 male young adult cats (all neutered), but decided we had room for one more. Our new guy, Rocky, is now 6 months old. He actually has an appointment to be neutered next week. Everyone gets along famously, but over the past 2-3 months, someone has begun to sporadically pee (not spray) on random items. (An arm chair, a throw pillow, a pair of my husband’s pants that he threw next to the hamper - that’s a separate issue lol, on top of a plastic storage tub.) We assume Rocky is the likely culprit, but have no way of knowing for sure, as we’ve never caught anyone in the act. If I have to, I’ll take all four of my guys to the vet to have them checked out for a UTI or other issues...but I thought I’d get some opinions on here first. I have no idea how I’d even begin to tell who is actually doing the peeing. Everyone is eating and drinking normally. I scoop the litter boxes daily. Are there any other behaviors I should be on the lookout for that might lend a clue? Should I hang in there another week and see if it stops after Rocky is neutered? Thanks for any ideas/thoughts/advice/insight you may have!!!
