Any recommend vet for hamster?
My robo got a lump below her neck

It looks big, reddish & bald
Bside than tt, she still eat & sleep as normal... Still exercise very hard during every nite
Bt fr wat i cn see she eat lesser & prefer soft food... Even hammie fav kuaci, she oso dun 'touch'~
I helping her 2 remove those shells & bedding I changed 2 tissue coz softer (no more woodshave, scare it might hurt her 'lump')
I google around, it said it was common 4 hamser when they gettin older...
My robo was 2 & half yr old liao... Her fur starting 2 get lesser w/in past few mth.
I need an experience vet who r expert in hamster coz i dun want send her in then die in there
