Before fixing them to the cage,I filled Miffy and Vinnies water up yesterday morning,When i fed them last night i noticed none had gone out of the bottle which is not unusal as they drink mostly at night,But i got into to bed and one of them was rattling the bars on the pen again nothing new they both do this when drinking but it went on for a bit so i went in, it was Vinnie checked the bottle and nothing was comming out so i tipped the water into a bowl they were both drinking for ages,I feel terrible ive took the bottle off and filled a bowl up which is funny cause they have never drank from a bowl before,This is the second bottle to stopp working in a few days
