I don't know what's going on, but there seems to be a lot of older kittens being found outside. Post Christmas dumps perhaps?
This is Mini, she was found outside at a shopping plaza recently and taken in by a lovely young man. He tried everything to find her home to no avail. He wasn't able to keep her so I took her in, she is very sweet and playful, about five months old. A lovely couple who just moved in on our street is going to take her. That will be neighbour #3 who has adopted a cat from me in the last year.
