Rodents also need activity and occupation for their good health.
Although exclusively herbivorous rabbits are not rodents but lagomorphs, they have rodent-like characteristics such as the continuous growth of their teeth. Other rodents are either vegetarians or omnivores.
Chewing food files teeth because the silica contained in hay and greenery ensures good tooth wear.
Naturally happy and curious, the rabbit needs to be entertained. He must be able to play, run, jump. Otherwise he gets bored and grows! A sociable animal that is easily stressed, rabbits need a calm environment and play is an anxiolytic for them.
To occupy him in a playful way, you can hide treats or hay in distributors or puzzles to motivate him to search, make him exercise and stimulate him mentally so that he finds a solution to obtain his reward.
Rabbits need to gnaw and chew and therefore all edible natural fiber toys are great for keeping them occupied. Grass tunnels and wooden toys in which he can hide or roll (like wicker balls) or gnaw are a source of amusement for him.

Other rodents also need to be physically and mentally stimulated so that they don't develop boredom-related tics. The ball is the ideal toy for all rodents: made of wood or wicker with a bell or a candy container, it is the most popular object of amusement for rodents who will nudge it. Intelligence games also occupy them for long periods of time: by hiding treats in a trap door, the animal will have to show cleverness to win the reward. A simple hanging ball of hay will serve as both play and food.

If the base of the rabbit's diet is hay and grass, the fresh plants provide it with nutrients, fibers and water guaranteeing good transit. Dried plants also allow him a good digestion. The rabbit likes to gnaw and remove the bark of the wood, especially those of the apple tree and the pear tree.
Wellness tips:
It should be noted that any new food must be gradually integrated into the ration to allow the fragile digestive system of the rabbit to adapt to it.
The rabbit must be exposed to sunlight to synthesize vitamin D useful in calcium metabolism. If he is not going outside, regularly expose his cage to the sun.
