my 1st cat passed away due to kidney stones cos dat time we were
all young n knew ntng n bought him Friskies. den weeks ltr on the
news, a dog had kidney stones cos of the food Pedigree. i boycott
Friskies, Whiskas and Pedigree since then.
den we changed to Science Diet for my 2nd kitty.. it was ok.
when i took my 3rd kitty (my boy now) to vet, he said he was over
weight n i asked the vet if Royal Canin LeightWeight was ok, n if
it will cos kidney stones. Vet said go ahead n said dun feed ur
pets w by-products.
best is to cook fresh food for the cats, healthier and less
preservatives.
