There's no way to do an operation as the tumour is so far inside the ear canal and could also be in the brain. She is too old at 18 months anyway.
As Orchid is scratching at the ear, she is cutting herself and losing drops of blood. We have to watch out for her losing too much blood and aside from that it's just a matter of time until her quality of life is too low and then we will have her euthanised. That could be months away yet though.
She is a sweet little girl who has always been very loving and a good mother. She continues to be a good mummy and friend to her daughter miniorch.
