You will need a great deal of commitment in order to own a cat as they do require some care (although not as much as dogs!) and can live as old as 15 years (or even longer in some cases).
Cats require feeding (daily), care and play time on a regular basis. You will also have to take into consideration, before getting your cat, that you will have vets bills to pay for annual vaccines, worming and if treatment is required for any illnesses. These bills can sometimes be very costly, but you can purchase insurance for pets it may be a good idea to shop around to get the best deal.
Before getting your cat, you should purchase bowls for food and water, a collar (if you want the cat to wear one), a bed (or pet quilt), a few suitable toys, and some food.
A kitten should be fed throughout the day 4 times with a small amount of food each meal, reducing to 3 times a day at 3 months old, then at 6-8 months 2 meals per day. Older cats (over 12 months) should only be fed twice in the day (usually morning and early evening).
Cats groom themselves, but using a soft brush on the cat, especially the long haired variety, will help to cut down the number of hairballs...
