Here's the history...we rescued him when he was two years old. No name, no history really. He is the BEST cat I've ever owned and we love him to pieces. Even non cat people take a liking to him! He's funny and full of personality and charm and is a lover! We had a female stray about the same age for a year prior to getting him and they get along famously, no problems ever.
He's 9 years old now and last year we moved to a new state. And rural. Where there are lots and LOTS of outdoor/barn cats. He does go outdoors (he insists) and comes back in to sleep and eat, play...
The other change is we did get a puppy last February. He's not crazy about the dog but he tolerates her. Just recently, about 2 months ago he started to pee along the wall about 2 feet from the 3 CLEAN litter boxes. Nothing would stop him until I laid ten feet of aluminum foil down. Then he started using another wall. Pee and poop! I banned him from the house for a few days, cleaned thoroughly with the enzyme cleaner and when the temps fell last week I let him in. More pee and poop in the same spot. I know it's him because the female cats pees are like crab cakes and his are the size of softballs.
I don't believe this to be a health problem but I am going to call the vet. I think it's 99% behavioral...he's VERY territorial. My last vet even said he is, just observing him.
Any advice?? I hate this. He's such a good cat otherwise. But, we just spent a ton of money remodeling our home and I can't have him destroying it with cat pee!! My husband is about to kill him!
