  • Royal Canin Calm Formula is helping both cats, but is not grain-free

    By on

    One of our cats started to exhibit behavior problems (bullying) due to anxiety/fear. Her vet recommended this food. It has helped both of our cats, the one bullying and the one bullied. However, I am not too excited about the ingredients. I have been feeding my cats a grain-free cat food, and the Royal Canin brand doesn't seem to do grain-free. Therefore, we are only mixing a portion of this food into our cat's grain free food. This amount seems to help. The Royal Canin Calm Formula cat food gets 4 stars because it is helping. It would have gotten 5 stars if it was grain-free.

  • Calming for the Stomach

    By on

    I haven't seen a psychologically calming effect; however, my cat also eats wet food, not this food alone. The great thing about this food is that he can take a full 1/2 tsp dose of Omega 3 and 6 fatty acids every day, which he needs for his granuloma skin allergy, and this food keeps him from getting diarrhea. I didn't realize this was the case until I switched him to a less expensive "special digestion" food and he got diarrhea until I switched back. Also, all four of the cats love this food.

  • Magical fix

    By on

    I have an anxiety ridden male cat that started urinating on area rugs and clean laundry baskets due to some changes in our home. This amazing food is like “ prozac for felines”! Stopped the problem immediately and created a much calmer, happier animal... highly recommend it! If I could give it more stars, I would!

  • I'm impressed!

    By on

    I ordered this special diet food on a Friday morning and it was delivered to my house on Monday morning. Not only was it shipped quickly, but Chewy had to call my vet to verify the prescription for the food before they could ship it. Thank you so much.

  • My cats love the calming food!

    By on

    I was a little worried about whether my cats would like the dry food because they were not fond of the wet food, but they loved it! And as this was the first time ordering from Chewy, we were also super impressed with their service.

  • Calm in midst of moving

    By on

    The Royal Canin - Calm Formal did what it said. The cats’ home was torn up with packing, moving cross country and unpacking in the new home. All things were not the same - the new Diet Calm Formula - did what it said it was to do. The cats are in their new home exploring their new environment. Still unpacking and trying to see where things will be in the new home. The cats are enjoying their new space.

  • Vet Script service

    By on

    Great service - ordered one day and it was delivered the next. This was also the first time that I ordered from Chewy and needed a vet script for the cat food. They handled getting the script from the vet name that I entered.

    Worth the price! My 1 year old cat is calm, cool and relaxed all day as I’m at work. She definitely is a happier kitty and very relaxed when she has this in her diet.

  • Fantastic food

    By on

    My cat is so much better using this food. He would stress out at any little thing. He is much calmer and sociable and doesn't stress out when we leave.
