We have a saying at our SPCA, "If Feliway doesn't stop a cat from marking its territory in one's home, then nothing can!"

Pros: Usually stops the spraying

Cons: Somewhat expensive

The spray works very well if you are trying to address urine-marking. Have also found it helpful to spray a little bit on towel that I put in carrier just before I put cat in to go to vet - seems to help with calming a bit. The spray works better than the diffuser.

FYI -- You can often find the spray at better prices on internet than you find in local stores

Pros: helpful

Cons: pricey - especially in local stores

Feliway is a calming pheromone for cats. It comes in spray form or as a diffuser. The spray form is effective for spraying carriers for trips to the vet, etc. The diffuser is effective to help keep peace in a multi cat home where one cat may be bullying other cats. It also can be hepful with urine marking. I have multiple cats and had urine marking occurring in my home. The Feliway diffuser was very effective originally; however, once one of my cats acquired a urinary tract infection and began urinating out of the litter box, I was never able to get the problem under control with just Feliway. I had to contact my veterinarian and use oral drugs to solve the problem.

Pros: calming agent for cats

Cons: not always effective

We spray Feliway on a cotton ball, let it sit for a couple of minutes (for the alcohol smell to dissipate) and place it in the cage with the kitty. It seems to help and calm many cats.

Pros: Easy to use, helps to decrease anxiety in most cats

Cons: Does not work on all cats

After the addition of the fourth cat into my household (which happened to be a female in an all male group), one of my male cats began spraying. He marked on the dog beds, up walls and I even found spray on a window. I tried both the diffuser and the spray and neither one seemed to help my problem. So I went to trying to limit access to the areas that he seemed to be spraying the most. The only improvement I did see is that my cats don't seem to "fight" with each other quite as much as they did before. I would like to try this product in our shelter and for transport of cats. I do think it would have a calming effect on them during transport.

Pros: decreases fights

Cons: my cat continued spraying
