Choose the right family pet: Insects
The local vet says: 'A spider bite is like a really painful wasp sting. And some tarantulas have barbs on their coat that will shed and stick into your skin, which, if they get into your eye, can cause conjunctivitus. I'd watch out for those things.'
Things to remember: Buying and keeping an exotic animal can be expensive because you need to have the right equipment to provide a suitable habitat for them to live in.
Family rating? Insects are low maintenance but they don't really have the same cuddle-factor.
