Question
PLS PLS PLS HELP ME

i have two twin male Tan Russian Dwarf Hamsters that ive had for 2 1/2 years now. one, that used to be the chubbier one is now skinnier and has lost a lot of weight. his tail is always soaked with diarrea and he has a bump on on his stomach when i turned him over, it is about the size of a pimple and a lighter color than his skin. pls tell me what you think this could be??? and the diarrea what does that mean ?? and what can i do for him?


THEN, my second hamster, his eyes are no longer bright red theyve had a whiteness in the middle of them and he never stops scratiching himself when i take him out to play with him. hes always cleaning and scratching. and yesterday i noticed it looked like his ear was torn or scratched badly and the other ear is slowly getting red as well. i compared it to his brothers and his ears are VERY much more red. what could this mean? it seems like his skin is burning and his ears are chapped???

IM SORRY I WROTE SO LONG, I WANTED TO BE SPECIFIC FOR YOU. THANK YOU VERY VERY VERY MUCH. <33


Answer
Even though my description says I don't take illness questions, the first hamster sounds like it has wet tail, which can be fatal. It usually causes the hamster to die of stress and dehydration. You can get some dri tail at your pet store as an antibiotic, though some hamsters will not recover with this formula. If you really want that one to live I would take it to a vet to get propper meds. The second one I honestly can't say. Try an expert who has more experience with illness questions.
