Bryson's favorite toy in his cage would have to be his stuffed raccoon cuddle buddy. He likes to pounce on it, wrestle it, and take it to the top of his cage, drop it, and watch it fall, and once he is satisfied with the thud, he runs back down, grabs it, and repeats the process.
Also, during cage cleaning day, he likes the vacuum hose. I'll point it at him, and he will come over and sniff it. It will suck up his whiskers, and he will shake off and popcorn a bit and I will go back to cleaning. Then a little bit later he comes back over and I do it again. He really seems to love it.
His favorite toys during playtime are:
My toes, especially if I have a nice and bright polish on.
The toilet, one day he actually flushed it when playing with the handle
The wall for wall surfing
The shower curtain, because it is fun to hide in
And I keep a poster tube in there and he likes to run back and forth inside of it, though, I did have to rescue him one day cause he's gotten so fat lately. He tried to turn around and got stuck. Needless to say, now he just backs out of the tube, runs to the other side, and does it again.
