When all our hideous building work is done, and I have totally de-cluttered our house ( no room to swing a shrew let alone a cat!!), I have promised myself and my 2 DS's some pets. Can't do dogs (out all day), DH allergic to cats, so I thought that rats or chinchillas would be the answer. But have only had gerbils as a child, know nothing about rats/chinchillas and would really appreciate some advice. How suitable are they for a 12 year old and an 8 year old? How to best keep them etc? Space won't really be a problem. TIA
