I know waking them up it's a bad thing and I feel really bad by ruining their tunnels to find them and check if they're okay, but I had a hamster die because I'd only check by seeing if he had eaten and drank water and when he went a day without coming out at night I thought it was because he was on his tunnels and didn't want to ruin them, something that had happened before and he was okay, but he had gotten stuck in a toilet paper tube and ended up passing away. Happens that my hamster (Alex, the lion) is an antisocial that hates human interaction and gets scared very easily. He hardly comes during the day and always sleeps deep in his tunnels. I can't see him because my cage it's 3 wood walls with a glass panel on the front. I'm very paranoid because of what happened to my other hamster (Motomoto), so when he goes a long time without appearing I dig into his tunnels till I find him, I try to be careful but I do ruin them a bit. It's there other ways to know that he's okay without having to do that? It's a camera really necessary then? Or there's any tips on bonding with him to convince him to come out on his own?
Edit - Thank you to everyone that answered! I think an important piece of information my post missed was that although his cage has access to natural light daily so he can tell when it's day and when it's night, maybe due to the country I live in instead of coming out at 9 or 10pm, he actually comes out at around 2-3am, which is the reason it's hard for me to see him when he's awake. I'll be looking into pet cameras, the one suggested came out at a very good price and I think it's a worthy investment for both my anxiety and Alex the lion's tunnels, and work harder on bonding with him. I've tried it before with not much success but even if he doesn't come to my hand but just put his head out if I make a little noise as recognition it's already enough for me.
