Cats exhibiting regressive behavior. . .

[TheFriendlyAnarchist]

Hey everyone. It looks like we have a problem. We have three cats, one is 16, one is 14, and one is about 5 or so. Lately though, they've all not been using their litter boxes, even when they're constantly kept clean.

The 15 year old one seems to be having the msot trouble. She was recently diagnosed with a hyperthyroid problem, and even with daily medication, is eating 4-5 times a day. But along with this, she refuses to use her litter box.
I'm not entirly sure what the 5 yr old ones problem is. I think he mostly uses it and goes outside, but he still refuses to use a clean box at time.

The oldest one has always had this problem, for the last several years (urinating on anything and everything).
Tonight, one of the cats peed on a bean bag that we've had for years. It wasn't new or anything, but there was just a big puddle inside of it.

So DU, I call upon you for helpful ideas, suggestions and experiences. My parents are just about ready to make these guys outdoor cats unless this stops. None of us really want to see this happen, but we're all tired of cleaning up after them.

1. ugh

they don't have the problem - you do. I don't have much advice, sorry - if this has been an ongoing long time issue it's going to be a bitch to solve. Maybe keep them locked out of most rooms of your house so at least those rooms are free from thier "additions"?

2. First, have the older one checked for diabetes

Extreme hunger with weight loss, thirst, excessive urination (usually inappropriate) are symptoms. Generally, peeing outside the box is a signal that they need a vet check.

Second, older cats may need lower sided litter boxes due to stiff joints that make it hard to get into and out of the box.

3. You really do have a problem there

You need to ask a professional. And, you definitely should not get more cats.

Try different cat litter and moving each litter box to a different location. Do you have 1 box per cat?

I agree with the above poster...one or more may have diabetes.

5. Cat Attract litter

You should try some of the Cat Attract cat litter. Also, take ALL these guys to the vet to get them checked out, but especially the older ones. Lots of types of illnesses can cause cats not to use the litter box. Good luck!
