Hi Shelley, thanks for answering.
I dont know what he ate in the past, but he eats 9 lives plus care for
urinary tract health (dry) and a spoonful of 9 lives canned a day to mix
w/ the tabs. of brewers, bonemeal, and dess. liver. He uses premium
choice (ground clay) scoopable litter right now. we bought a 50 lb. bag
from the place where we adopted him. He actually seems to be gaining
weight since we got him, and hasnt vomited in about 4 or 5 days now.
I've been giving him kittymalt hairball remedy, and it seems to be
working!

thanks,
Melanie
