i use three on my hamster and he loves it, as far as the rolls go, you can just put in a toilet paper roll and hell love it, eventually it will be chewed to shreds but it can be replaced at not cost to you because you were just going to throw it away anyways so why not give it to him so he can have some fun, dont waste you money buying one from the pet store, to get his teeth gnawed down you can also give him a little bit of well washed carrot or buy him some unsalted, unroasted Brazil Nuts, leave the shell on and just put them in there, they are very hard and hamsters love to chew on them and that cause there teeth to stay in nice shape, also provide something wooden to climb on to wear him nails down because if they become to big than it is also uncomfortable as well.

4 or 6

Well, If these are for a hamster, I've gotten 3 and 6 before and my hamster wouldn't chew them she would just pee on them. I'd say that 1 is definitely the best.

1 or 5 but i would probly go with 1 kk hope i helped x !

I would go with one or three... They look good.

hmm.....1 or four...or both! =]

they all look ok though...
