Question:
I have a male (11) and a female (8) cats. They have shared a litter box for about 8 years, which has been in our Laundry Room for the past 5 years. They get along well most of the time. Both are fixed and declawed in their front claws. Over the last 6 months or so, one of the cats (believed to be the male cat) has occasionally urinated outside the litter box – usually in the same corner. Over the last couple of weeks, they have urinated in the middle of the laundry room where the litter box is kept – missing the box altogether. We clean the litter box about every other day. Lately, our male cat has also gotten extraordinarily aggressive with our female cat and with us. Sometimes she will instigate the terror. Very unlike them. Finally, we sleep with our bedroom door closed because our male cat likes to knock stuff off of our dressers and night stands or will walk all over us while we sleep. Over the last couple of weeks, our female cat meows in the middle of the night at our door until she is let in and then on occasion will cry more. My theory is that there is a male cat roaming around at night and she is trying to get his attention and this aggravates our male cat. How do we stop all of this madness? And what is the best way to clean up cat urine and get rid of the smell?
Answer:
So sorry to hear about your recent cat problems!
First, let’s talk about your older boy cat. We suspect he is the root of the problems, and is upsetting the routine and equanimity of the younger girl cat.
You should take your boy cat to be evaluated by a vet. At 11 years old, your cat is in his geriatric years and a lot could be going it. There are many aging-related maladies that could be affecting your cat’s behavior – see this article on senility and geriatric issues in cats. It describes a variety of age-related maladies and behaviors that can occur, many of which track with the behaviors you describe. Sometimes these behaviors are just due to aging. Other times, they may be due to a medical condition such as such as a urinary tract infection (UTI), which is very common in older cats and can cause some of the problems you are seeing. Arthritis is another possibility. The article says “Radiographic evidence of degenerative joint disease is present in 70-90% of cats over 10 years of age. Associated pain and/or dysfunction can result in reduced activity and mobility, aggression, altered interactions with the family, and/or loss of litter box training.” If your cat doesn’t feel well, he is going to be irritable and cranky, and won’t want to be bothered. It also may cause him to be more aggressive in seeking your attention because he is looking for help.
Now we aren’t vets, so we can’t say whether your cat has an underlying medical problem, but that is the first place to start. The behaviors you describe are not uncommon in older cats, and may be triggering the younger cat’s discomfort.
Some other suggestions and comments on your questions:
First, with two cats using it, the litter box should probably be cleaned every day. See our prior post on Cats Peeing in the Wrong Places. And although we haven’t used it, many people have found Feliway helpful.
If you take care of the boy cat’s problems urinating outside the box, the girl cat may follow suit. Cats often urinate in a place that smells of urine, so thoroughly clean anywhere either cat has gone.
We are sorry to tell you that the cat urine smell is indeed a big problem. There are a variety of enzyme products that you can get in a pet store, but they can be costly and some say they only remove the smell temporarily. A thorough scrubbing with apple cider vinegar and/or baking soda are among some of the best methods we’ve heard. If you have throw rugs that cats have urinated on, your best bet may be to throw those away – the rubber backing in rugs tends to hold the smell. For permanent rugs and upholstery, steam cleaning may help. At the end of this article, we’ve included a few links to pages that offer suggestions.
As for the female crying at night … if she’s fixed, it’s doubtful that she’s calling for suitors. She may simply be thrown into confusion by the older cat’s behavior. It’s also likely she’s annoyed by the closed door. Cats hate a closed door, especially when they think something is going on the other side. After having the male cat checked out by a vet, try putting him in a room by himself at night and allowing the girl cat in with you.
