We currently have fish and a dog and my DS has been begging for a hamster for months and I'm about to give in. But I haven't had one since a kid and my mum did all the donkey work I'm sure. As I no doubt will be doing now. Karma and all that ....BUT he has made a PowerPoint of info, costed up how he will pay for it to be fed and bedded and I feel like he's serious. He's 12 and struggles a bit socially and I think it could be good for him. But I'm not stupid either. I want to know what is likely to fall to me.
