Domestic long hair cat is often used to explain a non pedigree cat with long or medium hair. Domestic longhair come in all types of colour under the sun, tortoiseshell, tabby, smoke, bi-coloured. Due to the diverse heritage they usually have a good personality. They will exhibit their own individual character that will be formed in their early months by their surroundings and owners. Constant attention and petting is likely to lead to a friendly, home loving cat. The mixed breeding also means the domestic long hair come in a wide variety of body shapes and sizes, ranging from ten to twenty pounds (4 to 8 kilograms) though the males are normally   heavier.
The long hair comes from a recessive gene, so you can see short hair offspring from longhairs and vice versa from a domestic shorthair.
Cat sitters love them for their long hair, but this results in them not being able to look after their own coats, so need to be groomed every day. This is a crucial part of cat care. Often breeders advise that the domestic longhair be bathed every week or two. However many breeders believe that if they are regularly groomed and they do not venture outside that this is not needed.
Bathing is difficult with a cat, unless it is introduced as part of regular routine to a young kitten.
The very long haired cats are extremely prone to matted fur, particularly if they venture outside. In extreme cases so bad that they grow “wings”. The nastiest places for matted fur are under the legs and arms. This will aggravate the cat and hamper his movements and on a cat that often goes outside, could lead him being caught in bushes or trees. The cats forcing away, could lead to bald patches and sometimes injuries.  If the cat develops such matting, the use of a de-matting comb should detangle it. The domestic long hair may not like grooming, but regular combing will remove the mat and stop them reforming.
New cat owners may feel tempted to cut the matted fur away using scissors, rather than brushing it out. Take care with doing this, the skin may appear like a mat and you may cut the cat. If you feel you must do this, be prudent, advance slowly and take time. An alternative is to use special grooming electric clippers, but be careful with these as well. Best is probably to use a professional cat groomer if there is any doubt. Many professional cat sitters such as London pet sitting will demat the cat as part of their service.
The matted fur and uncleaned skin in the area can contain a lot of bacteria, so be careful if you cut the cat and if you do, rapidly cleanup and disinfect the area.
