We would love a cat. But DHs mum has a phobia of cats, and visits us 5 or 6 times a year for a few weeks at a time (we live in different countries). She has told the kids she would not come and visit them if we had a cat. Could we feasibly keep the cat in eg our upstairs bedroom when she came to stay, if there was a cat flap in there to the balcony? My childhood cats were athletic, and would have been able to scale a fence up to the balcony, but I don’t know whetherthat’s typical. Is there another way of keeping the cat out of a visitors way?
