@hublee91: i think you shouldnt try to put them together d since they fight till bite each other. but are you sure they are both winter whites? not russian campbell and winter white?
@ix3Rukia: buy a toilet let them sand bath if they dont sand bath on their own then you can take the sand and rub it on them
if its near the hips, its their hip gland
http://www.google.com.my/search?q=hamster%...iw=1024&bih=437this one is normal. its their glands to mark territory and it will be more oily than other parts
it will take quite a while if its very oily and your hamster isnt that good in sand bathing
i give hamlet a sand bath twice a day and sometimes he mandi kerbau
so i have to rub the sand in the oily areas
last time when i put sand bath in his house, his fur forever fluffy
due to lack of space and very messy, i took his sand bath out
(he tends to dig the sand out of the toilet, make the whole cage sandy sandy)
also i feel not good to put sand bath in his house cause i scared he sniff too much or bath too much and have respiratory problems
im also using alex bathing sand but if possible i wanna find one that is unscented
anything scented isnt good
also be caution when purchasing things developed for other animals on hamsters, however from what i read, chincilla sand bath is alright for hamsters
