Q&A
Q: Our 11-year-old
cat was just diagnosed as hyperthyroid. But even before this, she missed
the litter box. I wonder if there's somehow a connection. The missing
of the box has worsened in recent years. She mostly goes on towels, clothing
and other cloth objects. Just a few months ago, we added a kitten, but
I doubt that has anything to do with the problem. We keep the litter boxes
fresh. Do you have any insights? -- D.H., Tempe, Ariz.
A: Urinary tract
disease is among the medical problems that can cause your cat to miss
the box. It's possible, although unlikely, that hyperthyroidism plays
a role, according to Dr. Philip Shanker, of Campbell, Calif. (near San
Jose).
With the limited
information you've offered, it's impossible to pinpoint the reason for
your cat's long-term elimination problem. In addition to a possible medical
explanation, your kitty may have a substrate (texture) preference. Try
placing a towel your cat has piddled on inside the litter box, then slowly
add litter to the box. As for litter, try either Yesterday's News (made
of recycled newspaper) or a unscented clay litter. There are also new
chemical-free wood chip litters, such as Luv My Kitty. After about three
days, remove the soiled towel and add another smaller towel. Eventually,
you can forget the towel in the litter box. Offer two options, one covered
litter box, the other uncovered.
Shanker, past president
of the American Association of Feline Practitioners, points out that hyperthyroidism
requires treatment. You have three options:
-- Medication. Some
cats can't tolerate the medicine (Tapazole) (cq), and patients must be
frequently monitored. This is the least expensive option but only controls
the disease, doesn't cure it.
-- Surgery. In the
hands of a trusted surgeon, this does work. However, most hyperthyroid
cats are elderly, and have other medical conditions, and hence a potential
risk. The cost is $600 to $800.
-- Radioisotope:
Radioactive iodine knocks out excess production in the thyroid gland,
curing hyperthyroidism. However, it may recur in about five to 15 percent
of cats. Vet offices don't offer this treatment, only veterinary schools.
The cat must be kept quarantined at the facility for several days. The
cost is $600 to $1,200.
