POLL RESULT


More than half of voters (58%) agreed with recent warnings from paediatricians that too much passive television viewing can harm infant development - and say they will not let their babies watch TV. A quarter of voters said they would still allow infants to watch TV, as some programs and DVDs are informative and specially designed to aid learning, while 18% of voters said they might allow their young children to watch the programs if there was an interactive element. View the full results and add your comments.

NEW POLL: Do you notice a correlation between your mood and your consumption of junk food? Have your say.

Goodbye to a not-so-sweet tooth

This week my cat went in for dental surgery and it's been a pretty stressful time. For me, that is, he seems pretty unfazed by the whole ordeal. He had a chip in the end of one of his canines, which are the pair of large teeth at the front of the mouth that cats like to show off when they yawn. (The vet offered to give me the freshly extracted, bloodied tooth. And no, it really wouldn't make a nice pendant.)

Domestic cats have naturally bad teeth, and what I've learnt from this experience is if you have your cat on a normal supermarket-bought diet, it's likely they'll have serious dental problems in the future. Cats are predators, and so, are prone to wolfing down their food as fast as possible, and store-bought biscuits aren't big enough to force them to chew - they'll come out pretty much intact when thrown up. (Fellow cat owners will relate when I say I have seen some vomits in my time.) And store-bought wet food stays coated to their teeth, leading to plaque and decay.

It's seriously lucky that cats don't have a sweet tooth. In fact, according to research done a few years ago by Joe Brand, a biochemist from Monell Chemical Senses Centre in Philadelphia, cats can't taste sweet food at all. They're the only known mammal to lack the 'sweet gene'.
