Q: Since we got a new HD-ready TV, our cat Porsche is fascinated with it, and David Attenborough’s wildlife programmes in particular. Why is that?
A: Like us, cats have binocular vision, but their eyes have adapted to enable them to cope with low-intensity light so that they can hunt at dawn and dusk. While they cannot see colour as well as we humans can, cats are stimulated by movement, and I suspect that Porsche is being stimulated by the moving animals she sees on the wildlife programmes.
There are now DVDs specifically for cats that feature a variety of eye-catching movements from insects, birds and mice, providing good stimulation for indoor cats.
