Just that I found a stray cat in a very very emaciated condition - and took it to the local vet on advice of RSPCA. It had no chip and they said it was an old cat and probably had renal failure - it was very underweight and they said they could run blood tests and see if it could be treated but it would need ongoing treatment and the poor thing was really suffering.
I said I thought it best if they put it to sleep and offered to pay - and honestly if I thought the poor creature had a chance of having a painfree and normal existence I would not have said that.
The cat was put to sleep in my arms and I feel bloody terrible about it - and wondering if I did the right thing. The vet and nurse said I had made the right decision.
