Hygiene can be a problem with long haired cats around the tail end. “Trousers” that are too long pick up dirt and debris which is often unpleasant and unhygienic. A trouser trim every couple of months will help cope with the hygiene problems.
Grooming problems caused by an ill, disabeled or traumatized cat can be the result of poor diet or neglect. Dull coat, dandruff and cat itchy skin can also be due to the cat being unable to self-groom due to illness, disability or trauma. A bath in quality cat shampoo and a thorough brush and blow dry can make a huge difference.
