|  There are many breeds of cat to choose from and also cross-breeds.
The advantage of a pure bred cat is that they have fairly fixed characteristics and temperaments and so it is more easy to find one that is almost certainly right for a particular environment and lifestyle. Buying a cross breed means that the characteristics and temperament are more uncertain.
It is important that first thought is given to the type or breed suited to particular circumstances. A long haired cat will require more grooming than a short haired cat, some breeds dislike being left alone for long period and some are more suited to children in the household than others.
Once the breed or type of cat has been decided, thought can be given to obtaining the cat from a breeder or other source.
 If selecting a kitten, look at all kittens in the litter to ensure they all look healthy and active. If one kitten is sickly it may indicate some genetic weakness or contagious illness which may be present in the others and so these are best avoided. The kittens should ideally be 12-16 weeks of age - kittens should not be sold younger than this.
Any kitten should be curious, alert, bright eyed with a clean coat. It should be inquisitive, not too nervous and not show any aggression. Beware of any kitten that has runny or sticky eyes, runny nose, sneezing, wet or dirty bottom, matted fur, seems lethargic or does not have a firm body. All of these things can indicate a sick kitten.
Once healthy and appealing kitten has been identified, it is best to hold it in order to inspect it further and see how friendly it is.
If looking at an older cat, perhaps a rescue cat, the same applies - look for one which is curious, lively, friendly with no signs of aggression, with good clean fur and bright eyes. |
