I've had both kinds... i ordered one on the internet and i got one from petsmart. they actually make them for dog or you can get the bigger kind for rabbits, etc. they need to be the larger hole so they get enough and have the stainless steel ends with the dual ball bearings. If you have a crate you can attached them to it, but I had my hubby build me a wooden thing, i hung on the wall and painted it the same color then put the bottle in it. it looks nice and maddie likes it. when i first got her back after she was missing/dead she was actually scared of it for a few days, Lewis had her a regular bowl. It didnt take her no time to catch back on. I did really notice the difference in coloring around her mouth from not using it. It really does make a difference...No More Wet Face |
