My 5 year old cat has once again peed in the house. He is healthy other than being a little overweight, no UTI, crystals, etc. I feed good foods and they have access to multiple water sources. He was neutered at 14 weeks. He's never had any urinary issues or behavioral issues associated with the litter box. I have three litterboxes and have always used the same sorts of litter. He still uses the boxes. I think the problem is that the previous renters had cats and I know their cats must've peed in the house b/c when we moved in, the basement had that cat urine smell, not terribly bad, but the smell left behind even after a thorough cleaning. So I spent a lot of money soaking the entire basement floor and even some of the walls with Urine Gone. Since we moved in, this particular cat has peed several times on dirty laundry. The first few times it was DH's fault because he saved the clothes, didn't wash them right so I'm sure the cat just smelled his smells and peed on them again. I had an intervention and trashed EVERYTHING he had peed on (I can smell it no matter how many gallons of Nature's Miracle it's soaked in!!). For a long time we've been good, no pee on the clothes, keeping the boxes cleaner, restricting access to tempting areas, etc. But then I discovered he peed behind our entertainment center. I noticed the dogs smelling there and yep, sure enough! I bought a huge bottle of Nature's Miracle, moved the huge enterainment center, and when I pulled up the corner just to see if it had soaked through, I found a LOT of damage. It always did smell a bit rank in that corner. I'm sure this is more damage from the previous tenants. So on one hand I'm annoyed with my cat, but on the other I can't hardly blame him since he's only peeing where someone else's cat already marked. I soaked the entire area, it's still drying now and when it does I will deep clean that corner, so it's not a huge deal. There was a lot of damage under the carpet, no way could've been caused by one cat marking there once or twice in the past 48 hours.
I'm frustrated because now the cat is locked in the basement (which is not so bad since it's big, the litter and food is down there, and the cats have toys, a huge cat tree, and a bench seat from a van as their bed), but I have no idea how many places in this house the previous cat marked and whether my cat will sense that and mark too.
