heck get a piece of PVC pipe that eth bowel will fit into and glue that down to th cage and then palce bowl in problem sloved bowl can com out to be cleaned and there still a set place for it . and if you can find a piece od pipe takerhte largest one you can get and recut the pipe so it fits in sections just make sure the edges are smooth and the bowl actually deeper than the pipe so it wll sit flat inside.
You know I should do this with the larger bowls and my snakes since theylike ot push theirs around.. Makes note ot do so over the winter lol butI personlly will use a silcone bases glue so it can be peelled off if ned be once in a while.
