Carol Hack, 54, runs a scuba-diving centre and lives with her husband Dave, a 57-year-old scientist, in Middleton, Cumbria. She says:
Within a few weeks of getting Pinky as a kitten two years ago, I knew she was special. I’ve had Somali cats (a long-haired breed) for 15 years — I owned eight at one time but now I’m down to six — and she’s by far the most intelligent.
For one thing, she can open zips. I have a zipped washbag where I keep cotton buds, which Pinky loves to play with. Sure enough, she learned to open it. At first she could only do it when I’d left the zip slightly open — she’d put her nose in the hole and push the zipper along. But then she started biting the zipper and pulling it along. She’s incredible.
