As someone who has lived with three feral-type cats, I can thoroughly recommend them.
The first was a feral kitten rescued from hospital grounds by my mum (a nurse) during a cull. I was nine at the time, and she grew into a handsome tortie and white.
The second was a semi-feral six month old who hid behind the furniture for the first few weeks till the affection of my other cat, Minnie, and curiosity drove her out. She grew into a proud huntress.
Now I have an ex-feral, Polly, who twists me round her paw. She has learnt the skills of a domestic cat (the pathetic looks to get her way) just as her previous hunting, scavenging and fear helped her survive as a feral. It took six months of gentleness and play before she finally sat on my lap and purred. She's now 20, and a sedate but playful old duchess.
I would recommend feral cats to anyone who has the patience to give them time to trust. Once they come round, they love with a vengeance.
Hurray for ferals!
