Water bowl flipping.

How about switching him to the Hamster-style water BOTTLE?

They hang on the cage bars in a metal holder;
and the bottle has a nipple-like outlet that the pet learns to "lick" for a drink.

He won't drink from it. Most buns won't I had on in his cage with the bowl for the first 5 months I had him and he never figured out how to use it.

I'll look into that locking bowl and the ceramic bowl. Chilli, Oslo's not much bigger than a rat, about 2 lbs.

Everyone's already said what I was going to say. I never had any luck with water bottles either and I've never had one that didn't leak. When I had a rabbit I used a heavy ceramic bowl for his water and a Quick-Lock crock for his food. Here's another link, this picture shows it better.
I LOVE quick-lock crocks and highly recommend them. They come in 2 sizes and many colors. They are made of heavier plastic than most of the other bowls like them. You can also get them off and on one handed unlike others that attach to the side. They take a couple tries to get the knack of putting them on, but in no time you will be a pro and won't even have to think about it. I use them for my rodents, birds, and dogs.

For water, I used something like the locking crock, but it fit into the corner. It worked really well. Munch was much bigger than Oslo (like 4-5 lbs), and he could've tipped over anything.

You said his food rots after a few days, how often do you clean it? I cleaned everysingleday... it was just icky if I didn't.

Also, Munch lived in a x-large wire dog crate, they're actually perfect for buns! They have a nice plastic tray and are safe from chewing, and bigger than pet store cages.

Oslo started out in a big dog wire crate too, but it was a hand me down that was falling apart so I bought a big bunny cage.
I think I'm going to buy that one in the second link Kblaix posted.

When I had guinea pigs (approx 3.5 lbs each) THIS was the type of bowls I used screwed down tight to the cage, and put a row of about 8 clothespins around it to keep them from throwing the bowl out of the ring. My ginea pigs seemed to like doing that alot, but the clothespins kept it in place and the pigs had no trouble standing up to the bowl. My cage had a plastic base so I put the bowl on the lowest part of the cage bars I could.

I don't know if rabbits are stronger than guinea pigs or not, or if rabbits will sit up to get in the bowl, but it might be worth a try.

good luck
