Hi, could I get some advice for my Hamster Lemon…
I adopted him about 5 months ago so I’m not sure about his age but he was really friendly and active. 2 days ago my dog (who sleeps over every other week since I’ve moved for Uni) Managed to pull off the blanket covering his enclosure and break through the top ( it’s a huge old fish tank with the lid on top when the dogs are here), I found my dog digging in the enclosure and when I got to Lemon he had smartly burrowed to the bottom of the deep tank and gotten away, but he emerged with a bloody eye and damp fur (I think this was from the water bowl being upturned since if my dog did grab him he probably wouldn’t have gotten away?)
Ran to vets *hysterically*, and he’s now on painkillers, antibiotics and eye drops, however, there are some other things I want to ask about – He seems to have lost his balance and is stumbling and falling when he does rarely come out now. His eye looks clear and clean now so I no longer think it is just from not using one of his eyes.
> I truly did not think the dog could ever get into the enclosure, and I completely understand how this is on me and should not have happened, but I want to help him as much as I can.
my hamster looks weird her eye is loosing coluer i dont no what it is and she is very smelly pls help me
I just got my hamster about 4 days ago, she is a Syrian hamster if that helps, we don’t know how she got hurt but it was in her cage either on her wheel or from her water bottle, her left hand got hurt and it has spots of a darker shade then what color her paw is, I have done my research and this is my last resort because I could not find anything anywhere, she does not have a limp at all and uses her hand on an average basis to pick up her food I am very worried for her, also, she does not seem to be in pain, she lets me pet her but not pick her up and she seems happy.
