My lovely cat is driving me crazy by peeing everywhere. She does use her litter box and never poos outside of it but she pees in other rooms. There are certain favourite spots e.g beside a certain door, behind sink, under chest of drawers, in corner behind my desk. I mentioned it to two different vets but they didn't really tell me anything. I am using vingear and a special spray to deal with the smell but sometimes my house stinks. A while back she sometimes had a little blood in her litter tray but this has stopped.
I let her outside and she has a cat pal (a male her boyfriend I think) who does come into the house and I have seen him spray. Please help I feel a little lost and clueless and am worried that it may be sign of some health problem.

Has your cat been spayed?
You should get her urine checked for infection.

Have you taken her to the vet?

A urinary or bladder infection in a cat will cause them to pee outside of their box, as well as cause the blood in their urine.

Blood in the litter pan is a huge sign that you need to get your cat to the vet! She could be suffering with any number of conditions. Please get her in...

Sounds like a bladder infection plus there could be a little bit of a territorial thing going on with the other cat too.She might just be mmarking her home to let the other cat know its her's.
