Would your parents be willing to read up on keeping roaches vs crickets? Dubia and Discoid (for places like FL where dubias are illegal) roaches don't fly or climb, are much easier to maintain, are quiet, and don't stink like crickets do. They're also more nutritious for your pet and far less likely to bring parasites. Their temp/humidity requirements for breeding also make them not an infestation risk in most places, in the unlikely event of escape.
