  my hamster has 2 wheels but i want him to learn to use his other wheel because its the silent spinner the wheel he is useing happens to be his cage yes i said his cage his cage is a crittertrail revoloution witch happens to be a wheel and a cage i added stuff on to it so the spinner will fit but he wont use his spinner instead he will use his cage when i lock up the cage wheel and he will climb up to the top of the cage and drop im scared he will get hurt how can i teach him to use his silent spinner?
sometimes they just don't like the wheel ad you cant really force him to use it but I would suggest you get a ball because they NEED exercise.
He doesn 't need to be taught. if he wants to run, he'll get the picture.
When hes ready he will ..
