Work on the tail with your brushes and combs before you decide to shave the cat's tail. It takes an inordinate amount of time for a long, bushy tail to re-grow, so don't clip it unless it is absolutely necessary. Leave the head and a fairly sizable ruff around the neck area. The anal area is particularly difficult. It can trap large wads of fecal material that are very difficult to shave due to their objectionable nature.
Some cats take a great deal of care.
Routine brushing and combing are the only answer unless you don't mind a long-haired cat shaved short two or three times a year. But proper tools and a little patience will make the job that much easier for everyone. All Rights Reserved.
