Rabbits are very social and playful animals, and they need a lot of exercise every day.
Playtime is very important for them both mentally and physically - they need to stretch their muscles and move in ways instinct tells them to, and they need to express their feelings and share with others (human or rabbit or other pets). They love to play games and to play with toys. This is something people who keep rabbits outdoors simply do not know, and is one of many reasons rabbits should be kept indoors with the rest of the family. A bored bunny is a very unhappy bunny! Knowing this also helps to (hopefully) protect the furniture and woodwork by giving the bunny something else to occupy its mind and destroy. Any toy rabbits destroy or throw around are the ones they like the most!
Rabbits need toys and playtime distractions to keep their minds busy Rabbits enjoy playing with other rabbits, humans, and other pets Rabbits respond to an invitation to play - you just have to learn how to invite a rabbit to play a game, and how your rabbit invites you (perhaps nipping your ankle and running away, or taking something of yours and hiding it, or playing hide and seek, etc) Rotating your rabbit's toys helps keep interest in them (when your rabbit gets bored with a toy, swap it with another one and put it aside to offer as a "new" toy later on) Rabbits have a sense of humor and will even play practical jokes on you - don't be surprised to find your car keys in the rabbit's water bowl if you're not giving him/her enough attention
For toys to be safe for your bunny, they must be untreated (ie, not painted or otherwise finished, no colored inks except soy-based, etc) and you must also watch to see which ones they play with and which ones they chew - you don't want them swallowing plastics.
