After trying for weeks without so much as a bite my bf suggested that we try a smaller mouse. I tried dangling the fuzzy in front of him without any luck so decided just to leave it on the floor of the tank, I looked in on him 10 mins later and it was in the process of being swallowed! :D
Thank god, I was really starting to get worried and didn't wanna have to assist feed! Although I doubt I would have had this stress if the pet shop had sold me the correct size of mouse when I bought him!
