Got a gecko for a two year old who loves a pajama mask. He doesn't really like it yet but his 3 and 5 year old siblings do. I bought them a kitten and an owl. They look big but fit well except the clasp is difficult to make. I've seen other strap closures that would be easier for kids and adults. Silicone with rounded protrusions merging into slots. But otherwise. Children love them.
