Worried About Your Cat’s Skin Health?

Skin health concerns are common and can appear anywhere on your cat’s body. Your veterinarian is the expert on your cat’s health, so you should always consult with this trusted advisor to find the best solutions for your pet. This specialized expertise is why Royal Canin works closely with veterinarians to develop formulas that support skin health.

Common Causes of Skin Health Concerns

Environmental Sensitivities

Pollen, plants and dust are environmental factors that can trigger an immune response in some cats.

Food Sensitivities

Your veterinarian may recommend a diet elimination trial to help determine if your pet has a sensitivity to certain proteins in his current diet.

Parasites

Your cat can pick up external parasites such as mites, fleas, ticks and lice from contaminated sources, both indoors and out.

Infection

Kittens, older cats, and cats that have recently been ill may be more susceptible to bacterial infections that can lead to skin health concerns.

How Can Nutrition Help?

Your veterinarian may recommend a Royal Canin Dermatology formula for your cat. These special formulations can:

Support digestive health by regulating movement through the GI tract and supporting balanced digestive flora

Support the skin’s natural protective barrier

Aid cellular health with a complex blend of antioxidants.

Promote healthy skin and coat by providing long chain omega-3 fatty acids in the diet

Find The Perfect Balance

With a dry and wet feeding routine, dry food supports positive oral health while wet food supports healthy hydration.

Autoship

No chicken=Big difference

Our cat was having a lot of stomach issues so our vet recommended we try a food that wasn’t chicken based. Thought we were buying healthy food before, but the percentage

Our cat was having a lot of stomach issues so our vet recommended we try a food that wasn’t chicken based. Thought we were buying healthy food before, but the percentage of chicken was still high. This made a huge difference! She has more energy, healthier skin/fur, and her appetite is back. Worth the money!

My cats actually eat this dry food, thank goodness!

Since this is a prescription food, of course I thought my cats would hate it. But they don't! Big win!

Excellent food for cats with digestive problems

I have 2 cats that are now on this kibble and both are doing wonderful. One cat in particular was having a lot of digestion problems, but now after changing her

I have 2 cats that are now on this kibble and both are doing wonderful. One cat in particular was having a lot of digestion problems, but now after changing her to this same diet as the other cat she is doing the best she has ever been. She is not hiding anymore and is now a happy cat with proper poos.

Cat Did Not like It

Unfortunately my little girl would not eat this food. I tried both the rabbit and the duck since she does like the wet duck formula. Going back to the Purina Hydrolyzed

one of the bags was not sealed.

I was not happy. One of the bags was vaccuum-sealed, as usual; the other was not. I realize this might have happened during shipping, but it never has happened

Switch in single protein

So instead of mixing this duck protein in with the rabbit protein, I put the duck formula in a separate bowl. My cats actually prefer it thankfully.

My Cat Vino Loves this food....

It is amazing how much my cat loves this after so so many other dried cat foods I tried out for my cat. My Cat Vino waits each morning for me to clean his dishes,

It is amazing how much my cat loves this after so so many other dried cat foods I tried out for my cat. My Cat Vino waits each morning for me to clean his dishes, etc. so I can give him a fresh bowl of this Royal Canin PD cat food. My vet recommended this for my cat. I just wish it did not cost so much! At least it is not wasted and Vino eats it. I free feed him so he has access always to his dry cat food.

Questionable Quality or Warehousing Control

My cat got rodent ulcers all the time until I put her on this stuff. It was a major relief that she actually enjoyed it over other foods. So after 1-2 years on this

My cat got rodent ulcers all the time until I put her on this stuff. It was a major relief that she actually enjoyed it over other foods. So after 1-2 years on this food, I order another bag from Chewy, and my cat straight up rejected it. The food smelt rancid and there was a visible difference in the appearance (shape, color, etc.) of the kibbles. So either 1) Royal Canin changed the formula to the point my cat hates it or 2) Chewy has poor warehousing and storage operations which resulted in this food going rancid (exposure to heat, not rotating old and new bags, etc.). Either way, I was very disappointed because this food is EXPENSIVE. I simply cannot take the risk of wasting more money on another bag. So I switched to another kibble.
