Help, My Cat's Licking Grout!

Cats can become obsessed with some odd things. You’ve probably heard of pica, but when a cat is ingesting cat litter or licking grout, something else could be going on. Nick T. writes:

My 15 year old cat Peyton licks the fireplace grout. The grout between the bricks. Why does he do that? The vet doesn’t seem to have a clue.

Nick, you should take a look at Peyton’s gums. If they’re pale and Peyton is acting lethargic, he may be anemic. Cats often ingest cat litter and lick grout when they are anemic. You’ll need to have your vet do a complete blood count to find out for sure. This very specific form of pica has been linked to anemia. Treatments vary depending on the cause which we can't know without consulting a veterinarian.

Anemia is a symptom of a deeper problem, so it may take some veterinary detective work to root out the cause if that’s the case. This will include various blood tests and possibly bone marrow tests. There are two classes of anemia, regenerative and non-regenerative.

Regenerative anemia occurs when there is acute blood loss, not only to injury but also potentially from a parasite or an illness. Non-regenerative anemia is usually tied to a chronic condition, which in cats is often kidney failure. Both types of anemia are treatable, but they can have very different treatments. These should always be advised and administered by a qualified veterinarian.

If it isn't anemia, it could be stress related. Have there been significant changes in your household of late? If so, those could be driving Peyton to develop some unusual behaviors. We have a previous post on pica here. Though it doesn't cover the grout-licking variety, it may give you some insight into other possible causes.

We wish you and Peyton all the best!
