Ask the Vet


Dear Dr. Schelling,

I spend a lot of time in my garden this time of year and enjoy the company of my cat Annie while I weed. Last week I noticed Annie was licking herself like crazy over her shoulder and neck area. When I looked closer at her, I found a perfectly round hole under her wet fur. I first thought it looked like a bullet hole or a bite wound. I cleaned the area as best I could with some soap and water but it did not seem to heal. When I checked again today I swear I could see a little white caterpillar inside the hole! I will make an appointment with Annie’s vet, but am worried sick about her and scared I will catch something from her.

–Caterpillar in my cat
Dear Caterpillar in my cat,

You don't know how close to right you are with your diagnosis of Annie's wound. More than likely your cat has been infested with the larvae of a Cuterebra or bot fly. These flies lay their eggs around rabbit or rodent burrows where unsuspecting cats and dogs can encounter them. When the pet grooms, they can ingest or inhale the eggs which go on to hatch into larvae or young worms. These larvae move to the space under the skin, create a large cyst called a warble, and eventually burrow out creating a breathing hole. This is likely when Annie started to groom excessively and when you saw what you thought was a caterpillar coming out for air.

Taking Annie to the veterinarian is the right thing to do. It is important that you not try to treat this condition at home as grabbing the larvae or squeezing the cyst can lead to severe allergic reactions and even anaphylaxis in your pet.

Why does my cat sometimes dash across the room and attack my ankles?

Dear Erik,

Your cat is stalking. It is our natural instinct to stalk and if we don't have toys to mimic our need for catching wild prey we may start going after you. But no need to worry, you can channel this behavior towards something that doesn't involve your feet. "Sneak up" on the answer here.

BAMBOO CAT DE-SHEDDING COMB: This de-shedding comb does just that—de-sheds. It's no secret that I love a good grooming session and this comb does the trick, there is never a speck of loose hair left behind. My humans love having a fur free place to sit and I love the opportunity to be twice as sneaky without fear of leaving a fur trail of evidence behind. Just don't tell my humans.

FLING-AMA-STRING: The first time my human hung the Fling-Ama-String on the doorknob and turned it on, I was mesmerized and mystified for a moment. I had never seen anything quite like it. Then I sprang into action. I jumped. And pawed. And snatched. And grabbed. And won! What fun! The string—my nemesis—appears and disappears quickly. But I, the master kitty, am too clever for it, as I can anticipate when it will be most vulnerable to my full-on claw and tooth attack. The Fling-Ama-String includes a high-speed option for advanced hunters who want to take the game to the next level. For more sedate or older cats, the human can start and stop the device so that even the most mellow cat can join in the playfulness.
