HOW CAN I STOP MY HAMSTER BEING BORED?

Give him plenty to chew. Put some plastic plumber's pipes to crawl through, lavatory paper tubes, and those thick tubes they send posters in, into his cage. "Put him in a hamster playground once a day, perhaps in one of those large plastic storeage boxes, though make sure his play is supervised." Make sure your hamster has a variety of fruit and veg, as well as its mix. A variety of food is important to any animal in captivity. Don¹t overfeed. Just make it interesting.
