Comfort Zone60 Day Starter Kit; 1 Multicat Diffuser & 2 Refills; Cat Calming Pheromone; Reduce Stress, Aggression, Fighting, Urine Marking, Scratching

This is the best thing that ever happened to me and my little hellion. To be fair, he was abused when I got him out of the shelter two years ago, so he has always been a biter. I would be a biter too if someone put a cigarette out on my head at 6 weeks of age! (Yes, someone put a cigarette out on this little Kitten’s head! So I took him home. Cannot believe it, but that’s his history) But about two days after I plugged the stuff in, he’s just calm as can be. He sleeps for longer periods of time and he just cuddles up with me every single morning. He hasn’t freaked out or bitten since I plugged this thing in. I will never run out of it because I’ll keep buying it. And you should too if you have a problem kitty.

The pheromone diffusers are a necessity in our home. We have three cats that generally get along, but like to get scrappy with each other, too. These diffusers help keep the fighting to a minimum and help the cats to be less stressed. One of our guys has FLUTD and needs all the help he can get to stay stress-free and well. We have these on auto-ship so we always have them on hand. I've noticed that when we've run out in the past, the scrapping escalates.You won't notice a night-and-day change in your cat(s) in a day, but these do help in lowering stress and aggression over the course of a couple weeks and the benefits keep going as long as you keep using the diffuser. Each cartridge lasts about 30 days, have no scent, and are mess-free. We use one per 1250 sq ft.

These appear to work at times and not at others. As a result, we switched to feeding calming treats to the one problem cat. Won't buy again

Product does work but leaves an oily stain up the walls

This diffuser made my cat vomit upwards of 25 times in 12 hours—she threw up so violently that there was blood in her throw up and I had to take her to the vet to get X-rays and bloodwork done, as well as have fluids and anti nausea injections administered, which cost me well over $1000. This is marketed as a safe product but it is clearly not; multiple people on Amazon and on the internet more generally have experienced this as well. Unbelievable!

Works great with feral kitties too!

My 16-year-old disgruntled cat used to pee on carpets & bath mats. No longer! Plugged in, peeing stopped. Ran out for awhile, peeing started again. Plugged back in, peeing stopped. That's scientific enough for me. Kitty seems happier as well. I wouldn't recommend this product lightly

I rescue cats/kittens and built a house just for that 10x10x16. I have one female cat who seems stress out hissing at everyone. The other cats are looking at her like she is crazy and give her a wide area, so I bought the two pkg diffuser, she is still one crazy lady.Then I bought collars figuring they are up close (around the neck), much better, no more hissing or acting like a nut. Still even though she seem healthy as can be, I will take her in for a check up, just to be on the safe side of cat ville. Collars work better.
