My cats hate to be brushed.

[pompoennetje]

But they both somehow (No idea what the reason could be) hate to be brushed.

Suki, she has semi-long hair. A mix between a tabby and a Maine Coon. She has no undercoat (is that even the correct word?) So first I thought I used a brush that was too sharp for her? But no matter what kind of brush I buy, she hates it. (she'll end up biting and walking away. Holding her makes her pissed off). So I gave up on her.

Hiro, A white with black kitty, who has an undercoat. Hates to be brushed as well. His fur is thicker and less softer. And whenever I try to bruh him he uses his paws and nails to grab onto the brush to bite in it.
Makes it hard for me to brush him. gonk

Anyone else has this same experience with their cats?
& Should I just let them take care of their own fur? I mean, things are getting a little bit too hairy here in the house.

Annabelle doesn't like it, so what I tend to do is give her some catnip before hand so she's euphoric and 'high'. Seems to work pretty well, she purrs like a little monster.

Otherwise, show them tough love. Take them into a designated room, hold them by the scruff and run the brush over them for a few strokes every day. They'll get used to it. Maybe they'll never like it, but eventually they'll learn that it's not a bad thing at all. Do you have them on a feeding schedule? If so, brush them right before you feed them so brushing=food.
