I have put an update in the general rescue section, but here's a little more info about them.
I trapped them, along with six others of the colony, last November. Fred was totally unhandleable at that time, but has become much more calm and playful. Victoria was initially very aloof and untouchable, but very beautiful; she now craves attention. From the beginning they were very fond of one another and would sit together like husband and wife, watching over the young kittens. I suspect there may have been a more complex family structure than I initially thought. (I first thought they were two generations of kittens from the same mother.)
Homes fell into the laps of the younger ones and Winnie who was the same age as V and F, but these two were overlooked. They have been spayed, neutered, wormed, but not vaccinated. Four other members of the colony have been tested for FeLV/FIV and been negative; they were tested by their new 'slaves'. They have been kept separate from my own healthy old cats, so have not been at risk of infection.
If any problems arose, I will always give advice regarding settling them and be willing to take them back.
If there are any issues I haven't covered, post here or get in touch with me via email.
I have a viewing and homecheck coming up for them, but it is possible that this will fall through. I will post the results here.
