i have a hamster called bernard he is three years old and he is very fat but now he never comes out of his little house because he is too busy pigging out with his hamster food and he is very scared of my dog because when she isnt chewing up my toy animals she is freaking out bernard by jumping up at his cage and trying to eat him but luckily i get there just in time to stop her from eating him oh and shes doing it now
