Stray cats spraying?
For the spot in the kitchen, use a vinegar-based cleaner to help cover the smell. Or, after cleaning the spot, mix 1/2 water and 1/2 white vinegar and spray over the area. Don't use an amonia based cleaner. Cat's urine smells like amonia, so a cleaner with amonia will usually encourage your cat to keep spraying in the same spots.



I'm not sure if there's anything that you can do for the outdoor areas. The stray cats will be attracted to your yard because they smell your own cats. My dad used to put mothballs in his garden to keep the cats out, but I don't know if you'd want to do this, since it would probably effect your own cats. How tame are the strays? Maybe you could take them to a local animal shelter?
Reply:Try a solution of half surgical spirit and half water in a plasitc plant sprayer bottle and spray the soiled area well. This will dispurse the fatty content in the Tom Cats urine so less likely to spray that area again. Report It
Reply:Try pputting pepper down outside in the places the stray cats are. Cats hate pepper and it is easy to put out! For the cat flap, try finding a doggy smell or put pepper around it so stray cats don't like it, make sure you get your cats used to it though!! :) You could try getting the stary cat problem sorted by calling the RSPCA or anything else.
