FURminator DeShedding Tool - Long Hair Cats

My cat only weighs 4 kilos, she's a small, compact breed with semi-long fur, but size S is way too small for her. The micro-knots still stay in the undercoat, as the tool doesn't even reach there – the prongs are too short. I expected more.

While brushing my cats (I have quite a few), I felt like their hair was being pulled out (the sound it made). None of my cats were happy, and some even started meowing and hissing – they tried to attack the furminator. I really didn’t expect things to go this way, and I’m not sure if I’ll use it again.

The product does its job, but after using it 3 or 4 times, I already have 5 broken central bristles and I’m worried about my kitty.
