Old Syrian hamster

[Georgiaguildford]

Hi, I’ve just joined this group for a little bit of help. So recently my Syrian hamster has become increasing less active, she doesn’t want to come out of her cage much anymore, she does come to see me at the bars but she mostly wants to sleep. She’s eating but not as much as she use to, her furs a bit rough and messy (I think it may be thinning but I’m not sure), she’s drinking and chewing on toys I’ve left in the cage but her ears always seem to be back now and she’s a bit unstable when she’s walking. I’ve put it all down to old age because she’s about 2 years and 8 months old, can anyone confirm that it is old age only because I’m worried she might be unwell or hurting? It’s heartbreaking seeing them age☹️
