Actually i had a call like that last week. 3 kittens all black and all wait for it "sneezing" so it put people off. Not in our area so i got Folkestone CP to do major miracles and they went to a vet where they all have cat flu.. thin, worms and fleas like being eaten alive..
No wonder she couldnt sell them.
The lady told me she had them up for 60 quid each but realised that she wasnt going to get that.. so offloaded them to us..
We took in another 4 kittens yesterday 6wks old still at vets due to space issues, mum AWOL.. or already preg. Found in a garden hedge.. But obv did belong to someone as she was in good nick...apparently.. No one took them on as there was "no money in kittens nowadays".. Talk about livid..!
