The Maze

I made my rats a very nice and sturdy wooden rat maze!  I put Tinker and Oatis in it together to start, and didn't time how they did.  Then one month later I put Tinker in alone.  He got nowhere!  He went up and down the same wrong path for 20 minutes, so I took him out.  Though he isn't too bright (he's showed that quality other times such as attempting to steal food from Oatis instead of going to the dish where bigger pieces of the same food are sitting), but he is still very loving and friendly!  I put Oatis in and he zipped through in 2 minutes and 35 seconds!  He is a genius! 

Tinker: Hey!  Give me that cheese!

Oatis: No way!  I'm really hungry!
