I live in the UK and know there are many people who think the idea of keeping a cat indoors is odd and/or cruel. There are also many people who don`t like cats much and wish we would keep them indoors!
My experience of any sort cat ownership, before getting my Ebby, was minimal. We had a cat called Scobie for a short while when I was a child, but after he disappeared without trace one day my mum couldn`t bring herself to get another. My son and daughter-in-law have had four cats in total, all from kittens. Tieme was the first and they had him for about 9 years, he survived being run over on two different occasions but finally one day he never returned home. Similar story with littermates Bill and Ted, except they often did go missing for a day or two, but then Ted never came back at all. Bill tended to stay close to home after that but then quite a while later he disappeared also. I am glad to say though that they still have the fourth cat, Bella.
Of the cats in my street, the cat from next door was attacked by a dog but luckly was okay, one disappeared a while back, and just recently another one, Molly, who could be Ebbys twin, has gone missing too.
When I decided to get myself a cat, besides seeing the heartbreak suffered of having a missing and run over cat, it was the example of Pet Talk cat owners who set me on the road wanting to keep my cat as an indoor cat. I told the staff of The Cats Protection shelter that I wanted to do that and they were very helpful. Four months ago I chose Ebby with that help and so far so good. (I do have to admit that maybe it is Bob the hairy dogmonster who stops her running for the outside door, she would have to pass him first, and if and when she does decide to brave him it may be a different story! )
I have never had the problem of her running around like Milo and Millie do, I am glad to say! She appears content enough at being indoors, so far anyway and I just hope it stays that way!
