At 9 – 10 month leos reach sexual maturity

My understanding has always been that it was more like 18 months before they get to full size, and that before that age and a weight of 50-60 grams, they should not be bred. At 10 months, my girl still had a lot of growing to do; I've never heard of a leo being done growing @ 10 months before.

On a separate note, I see the OP is using sand as a substrate. That's not recommended, especially for juveniles, as it can cause impactions, which can be fatal. Tile, slate, newspaper, paper towels, etc, are all better choices.
