If you are not going to play with your rabbit, a playmate is ideal otherwise the rabbit is likely to get bored quite quickly. Two males will fight, as will two females so it is best to get one of each sex. However, make sure both the male and female are desexed as this will mean no territorial urinating - and most importantly, no unwanted babies!
Rabbits must always have a good supply of water on hand, as this will prevent dehydration or even death as particularly in summer, rabbits can drink up to a litre a day!
Lastly, rabbits enjoy having toys to play with such as shredded newspaper or pine cones. Even pieces of cardboard and ping pong balls can act as great fun for rabbits. If your rabbit licks you, this is a sign of great affection which reveals that your rabbit trusts you and is not afraid to be around you (at first they will be very timid when approached).
Remember, treated well, rabbits can make great company and they do not need to be a pest. If you are willing to give your rabbit some love and affection, they will certainly return the favour.
