There's a Swedish brand called Mjau (meow in Swedish) I sometimes buy
for Caliban that doesn't contain any grains. The contents listed for
every flavour are meat and meat by-products (at least 4% being the
flavouring meat), egg and egg products, minerals, vegetables and sugar
(I don't like that, so I don't give it very often). Their pages are only
in Swedish and Finnish, but here are their tasters. ;o)

Don't tell the cats that their food is manufactured by a company called
Doggy.
