1. Assess the situation: Before you begin, determine the severity of the matting and whether it can be untangled with a grooming brush or comb. If not, shaving may be the only option.

2. Gather your supplies: To shave a matted cat, you will need a pet clipper, a grooming brush or comb, scissors (with rounded tips), and towels or old sheets for catching hair.

3. Prepare the area: Choose a well-lit and quiet space to shave your cat; preferably with no distractions or noise, such as a bathroom or utility room.

4. Enlist help if necessary: If your cat is particularly anxious or uncooperative, consider asking a friend or family member to hold them securely during the process.

5. Calm your cat: Speak softly and gently pet them to ease their anxiety before beginning.

6. Begin brushing: Using a grooming brush or comb, start by gently brushing away any loose fur and small tangles around the matted areas.

7. Trim excess fur: With rounded-tip scissors, carefully trim away any long fur surrounding the mats to make it easier for the clipper to access them.

8. Secure your cat: If your cat starts squirming or becomes agitated during the process, wrap them in a towel, exposing only the area you’re working on.

9. Power up the clipper: Turn on your pet clipper and let it run for a few seconds so your cat can get accustomed to its sound and vibration.

10. Begin shaving: Hold the clipper parallel to your cat’s skin (avoiding direct contact) and gently shave along their body in short, even strokes to remove the matted fur.

11. Work from head to tail: Begin at your cat’s head and work toward their tail, tackling one matted area at a time. Be sure to hold the skin taut to prevent any nicks or cuts.

12. Take breaks: If your cat becomes overly agitated or stressed, take a break and soothe them with gentle petting or soothing words before continuing.

13. Clean up as you go: Frequently brush away the shaved fur from the clipper blade to ensure smooth and even shaving.

14. Check your work: Once all matted areas have been shaved, double-check for any remaining mats and trim any uneven spots.

15. Praise and reward: After completing the process, offer your cat treats and affection to help reinforce positive behavior and minimize stress from the experience. Regular grooming can help avoid future matting issues.

Remember, while these steps can guide you through shaving a matted cat, if you’re unsure or uncomfortable with the process – or if your cat is aggressive, resistant, or in pain – consult a professional groomer or veterinarian for assistance.
