What is the best bedding to reduce smell, and that is comfortable for the hamster
Cedar,pine and aspen bedding is bad for your hamster and some are allergic to it. Even if your hamster looks fine those beddings mentioned above cause respitory problems for your little hamster. You should always buy Carefresh bedding, it controls odor great and its good for your hamster. Most pet stores use this bedding.
Give'em your TP or paper towel core when you change it...they'll make their own. Fun to watch 'em nibble it down.
Cedar shavings is the best for all small pets. It has a good odor, repels pests, and the animals love it to.
There are recycled paper products (Carefresh is one) that you can use that reduce odours and are super-absorbant. Whatever you do, don't use wood shavings because the scent can cause respiratory problems in small animals.
I can honestly say the best thing to use for hamster bedding is plain toilet or kitchen paper. Its soft, warm economical and the most safest thing for little hammies to sleep in. One tip....rip the tissue up and throw it all over the cage and watch your little friend racing about stuffing it in his cheeks and carrying it off somewhere to make up his bed!! Hamsters are nesters and love to build up their on bed. It will keep you ammused for hours to watch him, and he will love it.
