UUGH....I have 3 cats...I used to have 4 but gave one of my females to a family member because of urinating problems. Now I have 3 (2 males & 1 female) and the urinating problem has returned...and yes, before you ask about the other one we gave to family I did catch her doing it several times. So back to the problem....one of my cats is doing this. I don't know which one. I have 2 male persians and 1 female maine coon. They have peed on a brand new chaise lounger (I have used 5 bottles of Nature's Miracle trying to get it out....to no avail...I'm about to try a professional cleaning service)....and now I just found out they peed on my printer Yes...a scentless plastic computer printer (one of those expensive ones that prints photos)...well it's in the trash. I also found 2 pillows peed on...and if I leave dirty laundry on the floor they'll pee on that. I am at my wits end! The smell is nauseous...and I am an anally clean neat freak...so this is killing me!!!! What can I do??? I don't even know which cat is doing it! I mean I can't leave a camera on 24/7 because this doesn't happen all the time. I am planning on having the professional cleaner come in and steam clean my entire house (it needed it anyways because I am just finishing renovations) and steam clean the chaise lounger. I am throwing away all the pillows and plankets they've peed on. I'm also buying a black light and going through my whole house and trying to find areas I may not have known about. And yes...the litter box is kept clean...using the same litter as always...same location for the past year....same food...same water....I mean everything has been the same for a year!
