Agreed Iam64- but very sadly people abandon pets all the time- ducks included, for so many reasons (as said above they are very messy as adults)- this is why animal refuges are all full to the brim.
So I am prepared to give them the benefit of the doubt about good first intentions.
We lost our beloved Thomas when he was about 1 year old. He had a collar on with our name and address and detail. We searched high and low- asked everyone to keep a look out, put notices everywhere with photos, and how distressed our little girl was, etc, etc. 2 weeks later at a coffee morning, one womand I'd never met said the elderly couple across the road (about 3 streets down from us) had recently got a new young black cat ... I went and knocked at the door- and first of all she totally denied they had a new cat. I politely explained what had happened and gave a description, and told her her neighbour said they had a new cat. She said that yes, actually they did- but it wasn't at all as I described. I asked to look at him and she refused. Then I clocked Thomas's collar on the dresser at the side- I barged in and picked up the collar and asked where he was. She said I could not see it- by then I was not going to take no for an answer- and there he was, lying on the sofa, and very pleased to see me. I picked him up and went. The next day I went to see them and apologised for being brisk- and offered to find them a new kitten asap to help them out. Oh no, she said, we only want a black one with a white patch on the front, and your cat was perfect. I turned round and said that if they were racist, I couldn't help, and banged the door on my way out. Little old people, and butter would not melt. Thomas lived to 19 and was the best cat ever (from a litter of kittens born to ferral cat in the heating ducts of the South Staffs hospital).
