Thanks for the uppiedate!!
I am sorry he is still peeing in the wrong places. That stinks.
I strongly suggest the Feliway plug in as long as you have ruled out a UTI or something.
My little Kloe was peeing in inappropiate places also but I bought a Feliway and then noticed blood in her urine and she went to the vet for a UTI and after getting that taken care of (Just last Saturday) and the Feliway in the room where she spends most of her time has helped greatly. **Warning** They are pricey!! I was going to buy 2 but one unit cost me $45!!! I was glad that the pet store only had one altho the price would have deterred me!
I got a refill for $13 on www.petedge.com so you might want to try there - might be cheaper to order it even tho you would have to pay for s/h across the border then buying it from your vet. I can't imagine how much it would be at my vet!
