Just found out my 10 year old cat has a tumour in his small intestine 
Treatment would involve more scans/x-rays and an operation. Possible chemotherapy.
However I have three children (including a baby) and we can't afford it really. Chemo would not be an option as his waste could be toxic. No guarantee an operation alone would cure him (and we don't know if it has spread yet) although for this type of tumour there is a chance.
Vet did say we could keep him comfortable and euthanise when appropriate. I'm so confused/torn/upset. Of course I want to save him but the treatment route seems like a big undertaking with three kids, financially and practically (and of course emotionally too).
Any advice would be gratefully received
