Recently I watched an informative television show with a cat behavourist. He was in a pet store showing misguided humans (they want a cat) what things they needed to buy. By the time they left the store, they had spent quite a bit of money. As a public service, I am going to list the real essentials.
First, get a cat. Why get a bunch of cat essentials if you don't have a cat? Would you buy elephant accessories before you get a pet elephant? Of course not.
Next item on the list is food. Unless your cat shares his food with a dog, the cheap food is perfect. If a cat is fed expensive food, he gets uppity. Ask any dog - they will tell you there is nothing worse than an uppity cat unless it is an uppity squirrel.
Cats need a litter box to take care of their business. As you can imagine, they are not particularly good at producing a sellable item. The show said to get two of them. Evidently cats think they need a 2 bathroom house. They only need one. Again, you don't want an uppity cat. The pet store has covered or uncovered litter boxes. This is a blatant attempt by the litter box manufacturers to make more money. Any plastic tub will do. A dog could probably find a free one in the neighborhood garbage.
The only cat toys they need is whatever you have around the house. Yarn, a ball, or a toilet paper holder are perfect cat toys.
Water dishes are unnecessary if your house has a toilet. It is also hilarious to dogs when the cat falls into the water. However, purchasing a water dish for a cat is acceptable.
If you want to buy clothes for a cat, go ahead. They love to wear clothing.
I would be remiss if I didn't mention catnip addiction. Cats are prone to getting this affliction. If a cat starts wearing sun glases, he is probably an addict and needs to go to cat rehab.
Good luck to future cat owners. However, why not reconsider and get a dog. Cats are unappreciative jerks.
