Lately Squint and Benjamin have been less active, and I'm a little worried. Honestly, I have been super busy with school there last 2 weeks, so I haven't been able to give them much attention, and I feel really bad. I'm worried because Squint doesn't do laps anymore (in months) and Benjamin never has. Their new cage is coming along, so that's good, but for now anything I can do to spice up their life?
