We tried all sorts. They don't like plastic and are not overkeen on ceramic (unless it's ours of course). Foxy carries lighter bowl in his mouth all over the house. We put some ham in a paper plate for him once and the plate ended up in my bed (after the ham disappeared of course). Instead of eating like other normal cats Maya licks her food and she always had to run after her bowl. .
