Today I set up my HOTBIN for the first time and am determined not to open it again for a week to see how the temperature goes. I have one worry. I have 8 destructive cats who can shred a gate post very rapidly and I don't want them to start on my new bin! Would covering it loosely with bubble wrap, leaving the air vents free, affect it's functioning? I see another cat owner has the same worry. I know my cats hate bubble wrap. Maybe this would help her, too.
