Dear Dr. Schelling,

Can I feed my cats raw or uncooked liver? I've heard conflicting things about the healthfulness of raw liver for cats.

– Caroline and her cat clan

Dear Caroline,

Use caution. Raw or uncooked liver is high in Vitamin A, and too much vitamin A can cause hypervitaminosis A, or Vitamin A toxicity—a painful, serious, and irreversible condition. Vitamin A toxicity is characterized by excessive bone growth which can impair movement and even result in paralysis.

Vitamin A is an essential nutrient for cats, and any good quality cat food will contain the right proportion of vitamin A. The more vitamin A you feed you cats beyond that amount, the higher their risk of developing vitamin A toxicity. For this reason, many people decide not to feed their cats raw or uncooked liver.

For more information on the causes and symptoms of vitamin A toxicity, and the limited treatments available for the disease, please read “Vitamin A Toxicity in Cats.

A healthy and happy new year to you and the clan!

My boyfriend and I are curious about cats’ yawns. We yawn when we’re tired or bored—but what about cats? By the way, we marvel at how cats yawn; it’s so . . . dramatic.

Dear Lucy,

Compliment accepted. There is some overlap between why cats yawn and why humans yawn. But we have our own reasons, too. Read all about them in this article WHY CATS YAWN.

EL GATO MUY LOCO CATNIP CIGAR: The El Gato Muy Loco catnip cigar is packed with the good stuff: 100% premium grade organic catnip. No pesticides, no fillers. Even my humans can tell the difference when they take the toy out of the package. The El Gato is long enough to grab and kick. Also, I like to attack it and dig my claws into it. If the kitty in your casa responds to catnip, get ready for a little craziness when you bring out the El Gato cigar.

WEST PAW ZOO REST CAT MAT: On a cold winter’s day—or any other day of the year—I enjoy curling up and settling in for a few zzz’s, or maybe a lot of them. One of my favorite places to do that is on my West Paw Zoo Rest Cat Mat. With its oval shape and plush sides, it’s designed to keep kitties like me warm, snuggly, and secure. I like the feel of my feline fur against the Cat Mat’s ultra-soft faux fur. The animal prints let me dream about the wide open spaces while snoozing in the comfort and safety of my own home.
