I have 9 cats, and I have a 3 year. old son and 3 1/2 month old baby daughter. I have been dealing with the same exact issue lately. I was just at the laundromat yesterday because 'someone' peed on my big comforter. Luckiy I have a waterproof mattress cover under my sheets or it would be ruined. This is the 3rd (or maybe 4th) time this has happened since the baby was born. I've had pee problems before that come and go but lately its been a mess. I get pee on my kitchen counters, stove, against my bedroom door, in the bathroom, at the back door..... it drives me insane! I love my cats but I don't give them the attention they used to get before the kids came around. I try to spend some cuddle time with them in the evening so they don't feel they have been 'replaced'. I'm probably upsetting them too when I push them away when they want to climb on me (I don't want fur on the baby, especially since I'm nursing). I'm trying to be better with them. I also use Feliway every night and I do notice a difference. You NEED to be consistant with it or it won't work. I need to order some more and I think I may get some of the diffusers that plug in as well. And make sure you clean up the pee really good.. I use the Natures Miracle for cats (in PetSmart in the cat area), that gets the urine smell out. I have 2 litterboxes (one is a huge plastic bin inside a cat litter chest) and I clean them twice a day (or more if they are smelly). I feel for ya!!!
Oh, something I have to do with our bedroom door is shut it behind us any time we walk out of the room, even if it's to go down the hall. I don't want anyone sneaking in. It's a pain, but I have to do it.
