I tried this product when one of my cats was urine-marking...got this one rather than Feliway because of the cost. Turned out to be a bad idea. I sprayed it only one time. My cats had an adverse reaction to this spray - fighting, one acted as if he were having visual hallucinations, just acting crazy. Symptoms went away within 18-24 hours and I never used this product again. Hopefully it has worked better for others.

Pros: none for me

Cons: adverse reaction in my cats

I tried this product and found sometimes it works and sometimes it dosen't. I don't know if it's the product or my cat just chooses not to mark that day.

Pros: cheap

Cons: Dosen't work.

With any of these synthetic pheremone sprays, I personally think it is difficult to tell whether they work. If you are dealing with this problem, you address the problem by buying out the shelves and use any/every product/trick out there. I think No Mark does help and it is less expensive than some of the other brands. I am afraid to stop using it as the alternative is pretty disgusting and can be quite costly. A $10 bottle of No Mark is worth it for the peace of mind.

Pros: less expensive than many of the other synthetic pheremones

Cons: n/a

Organic is great but only if it actually works. This product does not end marking behaviors. It is inexpensive but there are a couple other products that are so much more effective.

Pros: organic

Cons: doesn't work

Not sure how effective this product is. It seems to work at first but then the cats get use to the smell and will remark their spot despite how many time I spray.

Pros: Fair results

Cons: Fair results
