Mrs Biker used to keep Rats as pets. I must admit, it unsettled me a bit at first. But they were amazing. They are very clever and enjoy contact with humans a lot. They learn quickly and can be taught things. They are also a great deterrent for infestations of either other Rats or Mice. They also carry less disease than a feral Cat.
Must admit though, the sight of a Rat in my garden immediately sends out a warning sign. Is it male, female, pregnant. Has it built tunnels. Has it built a home nearby...or is it just visiting?
I'm sorta wiv Mrs Jacksparra about being wary and wiv Jacksparra about dealing with any threat in the right way. There is a balance here that can be dealt with in a responsible way.
There is a lovely lady in our road. She detests slugs. Can't bear them. She puts out slug pellets by the bagfull. She doesn't mean to harm Hedgehogs, she just wants to kill the slugs. I think we all know what really happens.
I guess it will take some time before we (humans) realise the balance of nature and only take appropriate action as and when it is required.
We could just pursue Rats to near extinction, or learn to understand how and when we need to take action.
Realise this may be controversial, but hey, it's me!!!
