Grooming your cat on a regular basis will remove any loose fur that could end up in the cat’s digestive system, causing constipation, fur balls, and discomfort that can also result in your cat throwing up on a regular basis.
As a cat grooms itself by licking its fur, quite a large amount of that fur ends up being swallowed and when this is combined with the food in its stomach fur balls develop that need to be eliminated one way or another.
Longer haired cats obviously have a bigger problem than those with short hair, and they will need a lot more grooming to remove loose hair.
In addition to removing the loose fur, grooming can also get rid of any fleas that might be on your cat. While there are good flea formulations on the market, this regular grooming helps keep your cat in better condition and it also allows you to check if there are any other problems that might need attending to, particularly with tomcats as they get into fights with other cats that can lead to sores and infection.
If cats are living near farmland and they venture out into the fields they can get ticks in vast numbers in a very short time and grooming helps to remove a lot of these before they can cause too much trouble for your cat.
Grooming with a good cat comb also stops the fur from knotting. If left unattended for too long, and particularly with cats that have long hair, this knotting can get so matted that they need to have the fur cut to remove it. Knotted fur can form into hard lumps that can cause distress for the cat.
Regular grooming and good nutrition will ensure that your cat has a nice shiny coat, few problems with constipation and fur balls, and less chance of getting any other skin related problems.
