I’ve seen alot of videos about timing rats but they dont really work, so maybe you guys have some tips that worked for you! They always lay in the same box and dont do much except sleep, eat and drink. They hold on for life on the bars of the cage when i try to pick them up and they got very stressed when i were in the bathtub with them so i dont really know which method i should use. I dont like picking them up cause i dont like them being uncomfortable with it. What should i do?
