Here in Canada it is not easy finding reasonbly priced rat toys. I can build a corral , make cardboard box condos, but alot of rat toys comes from the U.S., and given the dollar rate, well, it can be pricey. I have made some stuff, but I recently came across a very cheap toy,,,brown paper bags! The boys love them, they shred them, rip them up. and snuggle in the bags, and brown bags can be gotten every where, ,,though,, when the boys are playing with the bags , it can be very noisy., carboard tubes from a hardware store(the tubes that are the centre of a carpet roll) are great. an old shoe or boot. an chuck of tree,( freeze it or nuke it, )to kill any bugs, which I do for bedding also.Just trying to keep my 3 boys happy.
