I've had pets all my life apart from a few years in early 20s. Mainly cats, but once a dog and 2 cats. I have been tempted to get a dog again to make me exercise - but I did find my previous dog much more of a tie than cats. You know they are waiting for you to come home, and feel guilty if I stayed out later. Cats don't care so much if you're late home, as long as they have some shelter and food.
Whn we moved to our current rural home 18 years ago we asked the local farmer if they had any spare kittens. He rang me to say one cat had had 3, come and choose which 2 we want. He would drown the other!!! Of course we insisted on having all 3. Flash, Candy and Rosie.
Just a few months later, one cold October afternoon, torrential rain, I thoguht I heard a faint miaow. It was a tiny tabby kitten huddling under our car, so cold, starving, wouldn't have lasted much longer. So then there were 4, Lucky came into our lives. We asked everywhere and no one knew where she'd come from.
We had many very happy years with theses loving cats, growing up with our 2 sons, part of the family. Then they gradually all have died over last 3 years. After 2 went, we got 2 rescue kittens, and have just got a second pair, so we are 4 again! No doubt they will be the last kittens we have, so are making th most of them.
