I have a long haired hamster I am not sure of her age but I do not think she is more than a year old... anyway last night I cleaned her cage and she was fine but tonight when I took her out to play with her I noticed that a massive lump, about the size of the top of my thumb so just under an inch, has formed on her neck and chest just between her front legs.
The lump does not feel like it could have puss in it, it feels far more solid but not like bone...it kind of feels like a bouncy ball. She continues to act very normal and it does not seem to cause her any pain when she is picked up. I have done some research on this but no one came up with a definate answer. If anyone knows what this could be and if it is a serious condition if you could please leave a response we would greatly appreciate it. no "she's going to die" tho please.
Thank you
