Drs. Foster & Smith CRAN HEALTH Tablets are effective, good-tasting, reasonably priced, naturally derived urinary tract support for cats. After my 10-year-old neutered male's stream slowed down, I gave him methionine tablets until he normalized, then started on one of these tablets daily to maintain his urinary tract health. I crush the tablet with a mano y metate and mix into his wet food. Not only does he love it, Tarifa, one of my girls actually prefers his food with this mixed in to her own food, and I don't have to worry, because it is safe for all cats!
