I agree canned are not really good -- I would look at getting him some dubia roaches --- they are way better feeder and dont tend to give parasites / pin worms like crickets here is some info on dubias
Dubias

• Long life span
• Excellent nutrition
• Easy to digest
• High in protein
Convenient for you
• Odorless and soundless
• Will not infest your home
• Can be stored out of sight
• Easy to care for
• Cannot jump, fly or climb
you can keep them in a 10 gallon aquarium or tote and feed them dubia food - squash carrots apples strawberries --- they dont like greens much I have found--- you can order on line from many places like
