If course the first thing you need to decide is whether or not you want to get an adult cat or a kitten.
There are advantages to both.
With a kitten, you raise them from the time they are a baby so you have more control over training them.
Of course, each kitten will have a unique personality so one kitten may be harder to train than another.
The downside to kittens is they are a lot more energetic and prone to trouble.
Adult cats are usually harder to train and will likely have already developed their own behaviors - good or bad.
They are generally set in their ways and breaking them of bad habits can be hard.
On the other hand, adult cats tend to be less energetic and less hyperactive which definitely reduces the amount of trouble they get in.
If you are looking at kittens for sale, it is a good idea to pay attention to where they come from.
There is a much higher chance of health problems in kittens who have come from a bad environment or who were not taken care of properly at birth.
Finally, consider looking at kittens from an animal shelter.
These shelters are often over crowded and need the support of the public.
The kittens there are in need of good homes and lots of affection so you may find your perfect kitten there.
If not, consider checking the classified ads or internet sale sites.
That is the better option if you are looking for a specific breed of cat as shelters don't often have purebred animals.
