Cats love this food

My cats love this food and are always wanting more. I don't know that the calming ingredients are enough for my cat, but they do seem to help a bit. I still use a diffuser in addition to the food, to help keep my boy less stressed. I would prefer a grain free formula, however I have not found any urinary formulations that do not contain grains. Prior to my cat's urinary issues, I had been feeding what I felt was a better quality food for about half of the price. Overall, my cats like the food and I have peace of mind that he is less likely to have urinary issues while eating this food.

Wonderful product!

My cat had to have emergency surgery several years back, including stating nearly a week at the vet/emergency vet to recover. I opted to switch his diet afterwards to help avoid further complications. The vet had a sample of the urinary+calming food, and my cat loved it and has been on it ever since. He made a full recovery and has been healthy and happy since then! Sometimes, he even gets mail!

PLEASE BRING BACK THIS FOOD

This stuff was great and really helped my two cats not fight all the time. One of the cats has kidney issues and has to be on the prescription urinary food. This stuff was a life-saver and we miss it.

Works

Started using this food after my cat blocked (urinary). I had recently gotten a crazy puppy that was causing some stress for the cat. No more Issues. Dog is still crazy. Cat would not eat Science Diet food.

He’s to find

My cat has been on this for over a year and has not has a urinary tract infection since he has been on it. However my source has not been able to get this for several months. Can you tell me why?

Gives my kitty an upset stomach

Worked ok in the beginning but there was always something off compared to the other urinary foods. Now I am 100% sure I isolated my cat's upset stomachs/diarrhea to this food! Second bag, and definitely if I give him this food not combined with anything else it's a disaster. The calmness does nothing. Stick to the original Urinary or Moderate Calorie, also have problems since they changed the recipe, but still better than this garbage.

Excellent food - but so hard to find

My cat would kill for this food. He absolutely tucks into it every day. He had a life-threatening run-in with crystals about 2.5 years ago and not a so single problem since. Sadly the vet I was using to get this from has moved out of area and I cannot find a single place online that carries it. I've asked another local vet and they say they can't get it. Not sure what I'm going to do about that.

Question

My cat has done well on the urinary so calm food. My question is, do you still make the kind that says CALM on the bag? My vet can’t seem to get it, and online pet stores don’t have it.
