What Is the FURminator? (And How Is It Different from a Regular Brush?)
The FURminator is not a regular brush. It’s a deshedding tool.
What it is: A stainless steel edge with teeth that reaches deep into your cat’s undercoat to remove loose fur – without cutting the top coat.
How it works:
- The stainless steel edge catches loose undercoat fur
- Teeth spacing allows the top coat to pass through unharmed
- Your cat feels a deep scratch, not a painful pull
Versus regular brushes:
| Feature | FURminator | Regular Slicker Brush |
|---|---|---|
| Reaches undercoat | ✅ Yes | ❌ No |
| Removes loose fur | 80-90% | 30-40% |
| Daily use safe? | ❌ No (1-2x/week max) | ✅ Yes |
| Risk of skin injury | Medium (if overused) | Low |
| Price | $$$ ($40-50) | $$ ($15-25) |
The Pros – What the FURminator Does Well
I recommend the FURminator for the right cats. Here’s why.
Pro #1: Dramatically Reduces Shedding
The FURminator removes 80-90% of loose undercoat in a single session. Owners regularly tell me they fill an entire grocery bag with fur.
Real example: One of my clients has a Maine Coon who sheds enough fur to make a second cat. After one FURminator session, she sent me a photo of a fur pile the size of a dinner plate. That’s not coming off on her furniture anymore.
Pro #2: Cats Actually Enjoy It
Unlike slicker brushes (which some cats hate), the stainless steel edge feels like a deep scratch. Many cats purr during FURminator sessions. Some even lean into it.
Why it feels good: The tool mimics the sensation of being scratched by another cat’s claws during grooming. It’s instinctual.
Pro #3: Lasts for Years
The stainless steel edge doesn’t dull. You buy it once, and it lasts for the life of your cat. No replacement heads needed.
Pro #4: FURejector Button
Press the button, and the fur clump ejects. No touching the wet, staticky fur ball. This is a small feature that makes a big difference.
Pro #5: Available in Cat-Specific Size
The cat version has a smaller head and shorter teeth than the dog version. It’s designed for cat body contours and thinner cat skin. Don’t buy the dog version for your cat.

The Cons & Safety Warnings – Read This Before Buying
The FURminator can hurt your cat if used incorrectly. I’m not being dramatic – I’ve treated the aftermath.
Con #1: Can Injure Skin If Overused (CRITICAL WARNING)
This is the most important section of this review. Read twice.
| Overuse Consequence | What Happens |
|---|---|
| Brush burn | Red, raw, irritated skin from metal friction (like rug burn) |
| Bald spots | Fur pulled out before it was ready to release |
| Skin irritation | Redness, flaking, discomfort that lasts days |
| Brush fear | Cat learns to run and hide when they see the FURminator |
⚠️ CRITICAL VET WARNING:
*”Use the FURminator 1-2x per week maximum – even during peak shedding season in spring and fall.*
Never daily. Never every other day.
I’ve treated cats with brush burn so severe that the skin was raw and bleeding. Every single owner said the same thing: ‘I thought more brushing was better.’
It’s not. Set a calendar reminder.”
— Dr. Allona Jackson, DVM
Con #2: Not for Daily Use
The FURminator is a weekly tool, not a daily brush. For daily maintenance (the other 5-6 days of the week), use a slicker brush or rubber brush.
Con #3: Expensive
At $40-50, the FURminator costs 2-3x more than basic brushes. For budget-conscious owners, there are alternatives (see comparison below).
Con #4: Requires Technique
You can’t just hack away at your cat’s fur. You need:
- Light pressure (imagine brushing a balloon)
- One pass per area (don’t go over same spot)
- Direction of fur growth only (never against the grain)
Many owners press too hard. Don’t be that owner.
Con #5: Not for All Cats
| Cat Type | Should You Use FURminator? | Why |
|---|---|---|
| Heavy shedder (Maine Coon, Ragdoll, Persian) | ✅ Yes | Benefits outweigh risks |
| Short hair, heavy shedder (British Shorthair) | ✅ Yes (use short hair version) | Effective with lighter pressure |
| Normal shedder (Domestic Shorthair) | ❌ Probably not needed | Overkill for normal shedding |
| Cat with thin skin (Sphynx, senior cats) | ❌ No | Too aggressive, even 1x/week |
| Cat with skin allergies or dermatitis | ❌ No | Can flare up existing conditions |
| Cat who hates the FURminator | ❌ No | Stop. Use something else. |

How to Use the FURminator Correctly (Step-by-Step)
Most problems come from incorrect use. Follow these steps exactly.
Step 1: Choose the Right Day
| Season | Frequency |
|---|---|
| Spring (March-May) | 2x per week (peak shedding) |
| Fall (Sept-Nov) | 2x per week (peak shedding) |
| Summer | 1x per week |
| Winter | 1x per week or every other week |
Pro tip: Brush 1-2 days after a bath (if your cat tolerates water). Damp fur releases more undercoat.
Step 2: Start with a Slicker Brush (2 minutes)
Remove surface loose fur first with a slicker brush. This prevents the FURminator from clogging after two strokes.
Step 3: Use Light Pressure
Imagine brushing a balloon. That’s the pressure. If you’d pop a balloon, you’re pressing too hard.
Let the tool do the work. The stainless steel edge doesn’t need force.
Step 4: One Pass Per Area
Don’t go over the same spot repeatedly. One pass. Move on.
If you miss a spot, get it next week. Over-brushing one area causes brush burn.
Step 5: Brush in Direction of Fur Growth Only
Never against the grain. Never back and forth. Always neck to tail in smooth, long strokes.
Step 6: Stop After 10-15 Minutes
Even if more fur is coming out. Even if your cat seems to love it. Over-brushing is real. Stop.
Step 7: Clean the Tool
Press the FURejector button. The fur clump pops off. Wipe the edge with a dry cloth. No soap needed.
The Golden Rules (Post on Your Fridge)
| Rule | Why |
|---|---|
| 1-2x per week maximum | Prevents brush burn |
| Light pressure | Prevents skin injury |
| One pass per area | Prevents over-brushing |
| Stop at 15 minutes | Prevents irritation |
| Never on thin-skinned cats | Prevents injury |

FAQs About the FURminator deshedding tool for cats
Can I use the FURminator every day?
No. This is the most common mistake I see. Use 1-2x per week maximum. Daily use causes brush burn, bald spots, and skin irritation.
I’m serious. I’ve treated cats who needed veterinary care because owners thought “more is better.” Set a calendar reminder.
Is the FURminator painful for cats?
Not when used correctly. With light pressure and 1-2x/week frequency, most cats enjoy it – they lean in and purr.
Pain happens when owners press too hard or use it daily. That’s not the tool’s fault. That’s user error.
Can I use the FURminator on a short-haired cat?
Yes, but buy the short hair version (shorter teeth, labeled for short hair). And use even less pressure – short-haired cats have thinner skin than long-haired breeds.
How much fur should the FURminator remove?
- Spring/fall (peak shedding): A grocery bag full over multiple sessions is normal.
- Summer/winter: Much less – a small handful.
If you’re still getting huge fur clumps in winter: Your cat may have a medical issue (hyperthyroidism, allergies, poor nutrition).
Related: Why is my cat shedding so much?
My cat hates the FURminator. What do I do?
Stop. Some cats don’t like the metal edge feeling. That’s fine.
Alternatives:
- Try a slicker brush (softer feel)
- Try a rubber brush (feels like petting)
- Try a self-grooming wall brush (zero handling)
Not every tool works for every cat.

How do I clean the FURminator?
- After each use: Press FURejector button. Fur pops off. Wipe edge with dry cloth.
- Weekly: Run under warm water. Dry completely.
- Monthly: No soap needed – water is fine.
Never: Submerge the handle in water. The ejector mechanism can rust.
Can I use the FURminator on a cat with mats?
No. The FURminator is for loose fur only, not mats.
Using it on a mat will:
- Pull your cat’s skin painfully
- Not remove the mat
- Potentially injure your cat
For mats: Use detangling spray + slicker brush. For severe mats, see a vet or professional groomer.
What’s the difference between the cat and dog FURminator?
The cat version has:
- Shorter teeth (cat undercoat is shallower)
- Smaller head (fits cat body contours)
- Different edge angle (designed for cat fur)
Don’t buy the dog version for your cat. It’s too aggressive and can hurt cat skin.
The Bottom Line – Should You Buy the FURminator?
Buy the FURminator if:
- ✅ Your cat sheds heavily (double-coated breed or seasonal heavy shedder)
- ✅ You will follow the 1-2x per week rule (set a calendar reminder today)
- ✅ You have the budget ($40-50)
- ✅ Your cat has normal-to-thick skin (not a Sphynx or senior with thin skin)
Skip the FURminator if:
- ❌ You want a daily brush (buy a slicker brush instead)
- ❌ Your cat has thin skin or skin allergies
- ❌ You’re on a tight budget (buy the Aumuca instead – under $20)
- ❌ Your cat already hates it (don’t force it)
My Final Verdict
“The FURminator is the gold standard for deshedding – but ONLY when used correctly.
*1-2x per week. Light pressure. One pass per area. Stop at 15 minutes.*
Used correctly: 5 stars. Used daily: 0 stars and a vet bill.
Buy it. Respect the rules. Your cat will thank you – and your vacuum will too.”

Rating: 4.5/5 stars ⭐⭐⭐⭐½ (deduction for user error risk – the tool is excellent but requires discipline)
