What are good dental treats, food, or toys for cats on special diets?
Hello. I do not know what might be available in Canada, but I highly recommend looking at this website for the Veterinary Oral Health Council. Click on the Accepted Products link at the top, then on accepted products for cats. It will list everything that is truly tested to provide results. Thanks for using PetCoach. https://www.vohc.org

Can I bring my cat to a Petco veterinary clinic for a wellness check?
Thanks for using Petco Pet Education Center, formerly Petcoach! Generally yes. It is always a good idea to call the specific clinic you are going to ahead of time to confirm that they are seeing patients for wellness exams. Best of luck!

What are common questions about cat health, food, behavior, breeds?
1. Cats seem to like me. I personally have four cats. 2. Cats love to eat! They also like to play and get love. 3. Cats are obligate carnivores, which means they need to eat meat to survive. Different cats have different tastes. My cats love tuna, and all cats love meat and fish. I have a cat who loves to eat potato chips, especially sour cream and onion ones. She will come running if she hears a bag opening. 4. It is never ok to give cats milk. They are lactose intolerant and can't digest it. It will give them diarrhea. 5. Again, it depends on the cat. Some cats like chasing balls, while other like chasing animals on a string or feathers. 6. The Persian is #1, followed by the Maine Coon, and then the Exotic. 7. The third eyelid removes debris from the cornea, and helps to redistribute tears across the cornea. 8. It's very important to have regular health checks at your vet and vaccinate your cats. Feed them a high quality cat food, and avoid human food as many are toxic to cats. Keep them at a healthy weight, and show them lots of love and affection. 9. There are a lot of differing opinions on declawing cats. Some people think it's wrong, while others don't see a problem with it. It simply depends on personal opinion. 10. Sphynx, Devon Rex, Cornish Rex.

Should I switch my dog and cat from Hill's Science Diet to Wellness?
In my opinion, Wellness is not as good a food as Hill's Science Diet and I agree with the recommendation of your vet's office to keep your dog and cat on Hill's. Hill's has better ingredients and is overall a better quality food. In addition, the truth is that grain free food is really a fad. Only about 5% of dogs have food allergies, and of these dogs, the major of the food allergies are protein. Grain allergies are actually extremely rare, and I only recommend feeding a pet a grain free food if they have a diagnosed grain allergy. I personally recommend keeping your pets on Hill's. I hope this helps!

My cat is five years old. What's the best food for her health?
Thanks for using Petco Pet Education Center, formerly Petcoach! There are several diets available in the market as you have probably noticed. I personally prefer Purina, Royal canin and Science Diet foods as they are of high quality and have research to back up their use. Any of their variations should be good for Maddi. Good luck and have a great day!
