Paw-Poorly

Our senior cat, Rosie has a very poorly paw and, unfortunately the vet thinks it may be a tumour. Biopsy is booked for the end of the month so we can only hope she isn't in too much pain (these are back blips and sad to say the paw is now twice the size so it's not looking great). Just want the final diagnosis now do we can do what we need to do to make sure she doesn't suffer too much.
