How frustrating! I can relate. I have two cats that can be spiteful - peeing and pooping in strange places if something is not to their liking. I see other people have recommended Feliway. I highly recommend this product!!! It is on sale right now at Drs Foster and Smith. Worth every penny. Worked wonders for us. Also, make sure you have multiple litter boxes. My final suggestion is to consider changing their diet. I put my cats on a raw diet and noticed a significant difference in their behavior. They are now much more relaxed and we haven’t had any accidents. It’s kind of a pain to make the “slop” but well worth it if it stops them from peeing all over the house. We feed our cats a recipe by feline instincts. (Buy the liver powder as the other option is pretty nasty!)I was very surprised by how much they changed once on the raw diet. The raw diet can also help medical issues related to their urinary tract. Good Luck!
Don’t believe that if an animal is spayed or neutered, they won’t “mark”. All my cats are fixed and I have a male that constantly marks his territory. Here’s what has helped:
- Feliway
- Not just cleaning, but replacing the litter in all of our cat boxes every 1-2 weeks.
- Use unscented litter.
- Never get a male cat again (poor DH is WAY outnumbered in our house now).
UrineGone (I buy it at Walmart) helps tremendously in getting rid of the smell, and I’ve tried just about every product out there.
Also, when we replaced our carpeting, we got special padding that helps with animal smells. It must help because now our cat doesn’t pee on the carpeting anymore.
Good luck!
