My 10 yrs old cat has urinated on the bed , 3 times in the last week! The only thing to change is our other cat died about 3 months ago , they were very close . I know about putting citrus in the area where they wee but it is a bit hard to do this on the bed. We have now got a litter tray which she is using but if we even leave the bedroom door open for a min she is up there doing it again . She has been spade and has not got a bladder infection .Any ideas would be grate .

Your poor baby is lonely and grieving. She misses her companion. My 12 year old hissed and fretted when I introduced my new kitten into my house,but now they play, sleep together, and groom each other. A buddy could help. Give her lots of love and try not to be harsh with her. She is trying to tell you something. the only thing i can say is keep the door closed if a cat pisses or sprays in a spot they always seem to keep doing it in that same spot no matter what you do i had a car and cats would always jump in and piss in the same spot everytime i left my window down i would open the door a cat would jump out and there would be pee always in the same spot even though i steam cleaned the carpet. just my analogy It sounds like she is trying to be the Queen Bee in the house , if you pardon the poor example (it's 5 am!). Do you have any other cats that sleep up there? Or com near it? Or you for that matter? Jealousy type thing?

If it is, pet her like crazy but when she starts to pee, squirt her with a water bottle with cool water in it. She'll get the message soon enough. Urinating in unusual places is a sign of urinary tract infection. Take her to the vet. I wish you luck. Try sprinkling your mattress with baking soda. Leave it there for a while and then vacuum. That should take care of the smell. You need to be SURE that she doesn't have a Bladder infection. Take her to the Vet! Peeing on the bed; it's a place where she knows you will be at some point and you will notice the pee on your bed. She's telling you something. This is her way of telling you that she is in pain realy bad or depressed about her lost friend that just died or both (or something else) You need to watch for these types of things. You said she lost a close one 3 months ago. She's DEPRESSED and doesn't know what to do. She wants her close one back with her but she can't. That's where YOU need to come in and show her lots and lots of love and cuddles. Please please find out for sure if she has a bladder infection or not! Take her to the Vet. Is there little blood spots in with the pee on your bed? (Bladder infection) but even if NO blood in with the pee, she's still telling you that something is bothering her and you need to TAKE HER TO THE VET and have the Vet help you find out what's wrong!
