my friend rick has a sweet 19year old cat,hes healthy for his age,will poop in litterbox but not pee.he pees allover his hardwood floor,it smells bad and is distroying it.plus he puts plastic sheets down,but bonzo goes underneth them.he rents his apt and he loves his cat and wants him to pass away peacefully at home,but others keep telling him to put him down.hes just old,in no pain,and eats and drinks fine.any hints for his floor.
The cat needs to see a vet and be checked for aUTI, crystals and thyroid, my 20 year old cat developed thyroid issues and stopped peeing in the box in the mean time tell your friend to purchase some puppy pee pads and place them in kitty's favorite spots.
I have a 19 year old cat, and she also would sometimes pee outside the box. One thing a cat behavior specialist told me is, as they get older, it gets harder for them to get in and out of a normal litterbox. Even though my cat is otherwise healthy, and can still go up and down steps-whose to say it isn't uncomfortable for her? And maybe not all the time, but just some of the time. Just like any person getting older-sometimes joints hurt and it's painful to walk-other days, things are fine.
What she recommended (and this has been working) instead of a litter pan, get a larger, less deep plastic pan the cat can use. I use a pan that is only about 1 1/2" high, so it is real easy for her to get in and out. It is also a bit larger than a normal litter pan. One thing I noticed is that even when she is in the litter pan, she can't squat down real well anymore. So sometimes, she would be IN the litter pan, but peeing OUTSIDE the litter pan! So this larger, less deep pan has been working out real well.
