No, my leo doesn't have MBD. But, when I was at my cousin's house, I saw his gecko. When I was holding him/her, it seemed like he/she couldn't crawl up. He/she kept sliding down, so I'm guessing that his/her legs are weak. Also I put him/her on the floor to see how he/she walks. (I'm just gonna refer to it as Bob and it instead of him/her) Bob can't walk normally. It looks like it pulls itself to walk and it drags its belly. It's very malnourished. Also, it looks like its back is kinda lop-sided... Whenever I go and see its cage, I never see a calcium dish in there. Does this leo have MBD?
