Fricka - we had a problem once with next doors cat coming in our cat flap at night and causing havoc, we had to get an ID chip on our cats collar so it only let our cat in, trouble was it took a couple of seconds to recognise and engage and she would get frustrated and walk off or be there headbutting a shut cat flap : (
I'd be peed off about 3 of someone else's kittens coming in too.
We're about to get a cat after not having one for 8 years as the boys grew up. Off to see a short haired tabby Mr Stripey, a 4 year old male at a cat rescue centre on Saturday. Apparently he was left behind when his last owners were evicted...
Pleased with my 21 days today, hoping to smash my last record of 30 days which was 4 years ago then I'll be in really new territory!
