Boo-Boo’s Story
by Certified Cat Behaviorist Rita Reimers
Do you have a cat with mouth pain? If so, you may notice changes in eating, behavior, or grooming habits. Mouth pain in cats is often linked to dental disease, inflammation, or injury, and it can quickly affect appetite.
When one of my beloved cats, Boo-Boo, developed a swollen mouth, I knew it would take time, antibiotics, and a lot of love to get him comfortable again.
Mouth pain can make eating a real challenge for our feline friends, but the right food choices can make all the difference.
Why Was Boo-Boo’s Mouth Sore?

One day, I noticed that Boo-Boo’s left cheek was puffed up. He was already on an antibiotic for an infection, but this was new. So, back we went to Dr. Faulkner (Dr. G wasn’t in), who had given Boo the medication for his elevated white cell count. This time, we discovered that one of Boo’s fangs on the right side was abscessed.

Under normal circumstances, we would have pulled it. But given Boo-Boo’s age and elevated kidney values, we had to treat it with antibiotics instead.
The swelling started to go down, but then one morning I sat down at the computer and noticed the tooth had fallen out, both good and bad. His mouth had re-swollen, and this time I was able to have Dr. Glenn take a look. He gave Boo a strong antibiotic injection, and here we are.
Boo-Boo had also dropped quite a bit of weight. He was down to a little over 6 pounds, which was especially alarming since he was 16 years old. I needed to make sure he ate, and ate well, so he could regain some weight.
The Challenge of Eating with a Sore Mouth

Boo-Boo tried to eat, but it was painful.
Cats often hide discomfort, so when you notice drooling, pawing at the mouth, or food refusal, it’s usually pretty serious.
Even with his mouth pain, Boo-Boo was still eating a little, which was a huge relief, but I could see chewing was hard for him. I wanted to make sure every bite was easy on him while the swelling went down.
His swelling improved significantly after the antibiotic shot, and Boo can now chew dry food and treats again.
Boo-Boo’s Favorite Comfort Foods
I quickly learned that texture mattered most when it came to a sore mouth. Food that required chewing was off-limits for a while.
Here’s what worked best for Boo-Boo:
-
Pâté with warm water: Turning his meal into a soft, soupy consistency made it irresistible
-
Baby food–style pouch meals: Smooth and easy to lap up, his favorite is Delectables Bisque
-
A little dry kibble when he felt up to it: I left some out, and he nibbled when he wanted to, letting him self-regulate
Other Soft Food Options for Cats with Mouth Pain

If your cat is dealing with dental issues, swelling, or recovering from a vet visit, here are some additional foods to try:
- Mousse-style foods: Airy and fluffy, requiring almost no chewing
- Lickable treats: Like Churu or a gravy-style meal topper
- Bone broth: Added to pâté to create a soft slurry
- Vet recovery diets: Such as Hill’s a/d or Royal Canin Recovery
- Plain meat baby food: Chicken, turkey, or beef with no onions or garlic
- Shredded poached chicken or turkey: Moistened with water, gravy, or bone broth
The Takeaway
With the right food adjustments, even a sore mouth doesn’t have to mean skipped meals. Boo-Boo is proof that a little creativity, and some extra TLC, can keep your cat nourished and comfortable while they heal.
Side note: Boo-Boo has regained 2 pounds, YAHOO!!!
