Recently I found two dead rats which had obviously been caught by a cat. I wish I'd taken photos but they were a bit gruesome so maybe it's just as well I didn't. In the past we have had a big problem with vermin. I much prefer Nature's way of dealing with it, rather than putting down traps or poison.
Alan, from North Birmingham Cats Protection told me that sometimes they re-home cats to stables. These would be cats which were either feral or just didn't want to live indoors.
I'm sure that there are many allotment sites all over the country which could offer these sort of cats an outdoor home.
All it needs is a couple of people at the allotment to commit themselves to caring for the cats every day.
I live quite near the allotments and am able to drive or walk there every day. Ken comes on the bus, sometimes twice a day. We do this whatever the weather, even when it's impossible to work on our plots because they are frozen.
It is an amazing feeling to know that cats which never had human contact before are gradually getting to trust us.
