No clips on my lid, like scott says, they can't get good leverage on it, and even with my light lid on the left side, it's a snug fit, and being heavier than them I doubt they could do more than lift it a few mm even if they could get good leverage. Had them and that lid 8 mths.
I see this question comes up a lot and I really like these water bottle holders from the petstore. One came with the bottle and one came by itself. I used those double sided sticky squares from 3M to attach the water bottle holder to the wall and then just take the bottle in and out easily. Of course, you’ll want to be sure you’re putting it in the right place because it’s a pain to move it.
(yes, my hamster makes his nest in the stupidest spot. He’s so cute)
Very cute poking his nose out like that But perhaps his nest choice is very smart (as long as the bottle doesn't leak! lol), he's got his drink right next to his bed . Would be a bit like us having teamaker or beer fridge next to the bed, lol.
Oh and good idea about using double sided sticky pads ,
