My son Will many of his summer days chasing and observing bugs. I bought him this little cage so that he could create mini temporary habitats (before I insist that he set the poor critters free). I find that it comes in very handy—and makes it so I don’t have to poke holes in the tops of every single jelly jar in our cupboard. Top entry makes it easy for little hands to drop in bits of grass and other furnishings. This also makes a nice birthday gift with a hermit crab or something.
