I got the idea from when I give them sardines. I used to mash the fish up with a bit of bread.
but they picked the fish out of the bread.
(they dont think much of boiled rice either, which is a pity, as I get though tons of the stuff)
Biscuits brown, I crumble into a small amount of hot water to turn into a mash, then add sardines, meatpaste, chopped meat, anything of that ilk.
its a nice change from pouch food, and they prefer it to kitty kibbles.
