I have 3 rats at present. Two girls - Magrat Garlick and Susan Sto Helit - and one boy - Russell. This morning, I decided to treat my brood to a new brain toy. I took an empty egg carton (the kind that only holds 6 eggs) and put some goodies inside. I then closed it up and put it in their cage.
It took Magrat all of 5 seconds to come and investigate this new object. Soon all three were there, desperately trying to pry open the box to get to the treasures within. Magrat started throwing the carton around, perhaps thinking that brute force might do it. It took them quite some time aEventually Susan figured out how to unclip the box to reveal all the nummies. Russell grabbed his and vanished into his hide-away to feast. But the girls... it had now become a personal vendetta! They didn't bother with the treats at all - instead it was all about making the egg carton pay for being so stubborn! LOL. The wrath of Magrat soon descended on the poor carton - she showed it! Now it is in various pieces, happily being used as bedding :)
