What kind food bowls do you use?

[Kfamr]

All of the above.

Nala has stainless steal as her elevated bowls,
Simba has plastic food bowls,
Ki has ceramics

Their water bowl is ceramic.

They all have stainless steel.

I don't use bowls- my dogs are free-fed and all eat out of a large gravity bin. I have found that they eat what they need and there is no fighting when they are not expected to eat at a certain time and stick to 'their' bowl. The only concern is the food becoming stale, so it is only filled about 1/3 at a time.
