So, our first hamster died after only 4 months (and several vets' bills!). We're super neurotic now. Picked up new hamster today, male, 5 weeks. Following all the instructions re leaving him alone to settle in, rest, not do too much etc. but the little chap has not stopped climbing the bars, running around in his wheel etc. Now instinctively, I think that means he's fit and healthy. But DD is still panicking after death of DH1 (that's hamster, not husband) and tho I keep saying he's just fit and healthy, she's worried that he's overdoing it. Perhaps she's even right. Any ideas, anyone?
