Please help I found a small sized lump on my male rats kneck, it is nearer his head than his legs and isnât too big but I did feel it and you canât really move it around and it seems to be attached to something. He has breathing difficulties which we took him to the vet for but nothing has worked and now I suspect it is the lump causing the problems!!! I donât have a lot of money to spend at the vets getting it removed and loads of medication if you know what I should do please help ASAP because Iâd hate for him to die because his little friend would have no one and heâs only a year old and so sweet. There is also no wound or anything! So please any advice would be amazing thank you!!!
