"Eight years ago, a long-haired stray cat decided to move into my home. I'm sure ya'll know how they do that... Anyway, at her first vet visit, I was advised to feed her Laxatone - essentially a petroleum gel - every day for hairballs or "You'll regret it."
That didn't seem nutritionally sound to me, since the gel can prevent absorption of nutrients, so I looked about for other ways to control or minimize her voluminous fur balls. I tried sprinkling psyllium powder onto her food, as a friend suggested, but that didn't work for us. Then I discovered Hill's Science Diet Hairball Control Formula Kibble. She's thrived on the kibble for the past 7 years, with at most one or two hairball incidents per year. In her case, the fur passed through harmlessly and ended up in the litter box.
This summer her food consumption dropped, and what little she ate often came right back up still in its neat little pyramid shape. She lost weight she couldn't afford to lose, being pretty skinny to start with. After thyroid and kidney tests found nothing alarming, my vet said she was probably just experiencing digestion problems due to aging. So I switched to the canned version of Hairball Control Formula, which is easier to digest.
Her appetite is back (in retrospect, I probably should have tried switching to canned first before coughing up $$$ for tests!) and she seems to be thriving once more. It comes in two flavors, chicken and seafood, and she gobbles down both equally. But the canned version doesn't seem as effective as the dry. She now battles with a hairball about once a month. Which is more than she used to, but still FAR less than one might expect from a cat with long fur. So, we're happy.
But I did want to call attention to the fact that Hill's recently changed the formula for the canned food, and that the feeding recommendation per 10 lbs. has increased from 1 1/4 - 1 3/4 cans to 1 1/3 - 2 cans. The moisture has increased from 76% to 78%...which is obvious because it's quite soupy. The difference in feeding recommendations is equivalent to having shrunk the can by nearly 1/2 an ounce. I'm concerned that if people don't carefully read the new label, they'll just keep feeding according to the old recommendations and won't realize their cat is possibly undernourished. So I'm using this forum to let people know.
Here is the Guaranteed Analysis per can for the old and new formula as found on the cans:
OLD: Crude Protein Min. 8%; Crude Fat Min. 4.8%; Crude Fiber Max 2.7%; Moisture Max 76%; Ash Max. 2.2%; Calcium Min 0.22%; Phosphorus Min. .11%; Magnesium Max. 0.023%; Taurine Min. 0.1%
*FEEDING RECOMMENDATION: Feed 1 1/4 - 1 3/4 cans daily for a 10 lb. cat. Adjust as needed
NEW IMPROVED: Crude Protein Min. 7.5%; Crude Fat Min. 4.0%; Crude Fiber Max. 3.0%; Moisture Max. 78%; Ash Max 2.0%; Calcium Min. 0.15%; Phosphorus Min 0.1%; Magnesium Max 0.02%; Taurine Min. 0.1%.
*FEEDING RECOMMENDATION: Feed 1 1/3 - 2 cans daily for a 10 lb. cat. Adjust as needed"
