I have two young balls in tubs with thermometer probes in them (these are generic thermometers, not reptile brand-name). They are supposed to stick to inside of the tub, but I guess in moving around, the snakes keep pulling them off. I normally don't mind sticking them back in, but they've gotten stuck to the paper towels and no longer stick.
I know tape is a bad idea, but these tubs are very temporary so I don't want to permanently glue them down, either. Any ideas?
