Rabbits love to snuffle around and forage for food. Rather than using a bowl for their nuggets or fresh food, try hiding the food around the enclosure, in tunnels and in/on hides to get their noses working. This will encourage them to forage for their food and prevent boredom and obesity. You can also try;
Rabbits are prey animals so to ensure they feel safe in their home, make sure you provide enough hiding places for them to nip in and out of. You can provide hiding places by using tunnels, stools and cardboard boxes. Tunnels are very important as this provides a substitute burrow and encourages your rabbit to be more active! You don't necessarily need to buy tunnels; using cardboard boxes from your last online shopping spree is all you need! Simply get one cardboard box and cut an entrance and exit or gather multiple boxes of different sizes and DIY them together to make an interesting tunnel network or maze for your rabbits to explore and have fun.
Rabbits are highly social animals and need to have the companionship in the form of another rabbit (rabbits can live in pairs or groups). No matter how much time we spend with our bunnies, nothing matches the company of another rabbit. We lead busy lives and even if we make sure to spend four hours a day with our rabbits, the other twenty hours is them being alone.. but if they live with another rabbit, they will never be lonely. Not only does it prevent them from being lonely, it always makes them feel safer. In the wild rabbits will live in groups called warrens, where they can snuggle up and keep each other warm and, most importantly, this helps keep them safe from predators. If a single rabbit is alone it can make them anxious, stressed and overwhelmed however, if they have company, that's another set of eyes to watch out for any potential danger, so that a single bunny doesn't have to be alert 24/7.
