I brush my cat at the very least every other day, yet she is still getting mats in certain spots - what to do?

Brushing is why you're getting mats. Longhaired cats should never be brushed - they need to be COMBED. Brushes do very little to remove the loose hairs of the undercoat which are the hairs that cause mats. They also pull out and break the topcoat hairs.

Use a good quality steel-toothed comb and thoroughly comb the coat at least every other day.

First, take her to the vet and see if she has any kind of skin condition that could be treated.

If she's totally healthy, well, some long-haired cats just get mats because they have so much fur. It's perfectly safe to cut the mats out (just be careful not to cut her skin or poke her with the scissors) - she'll look a little patchy but it's not dangerous at all.

You might also try switching from your normal brush to a metal comb that thins out the undercoat - you can find good grooming supplies at any pet store.

My cat gets mats on her back near the base of her tail. She is a DSH(domesticate short hair) and has an undercoat of fur that tends to mat. I bought a comb called a "furminator" and this removes the undercoat and gets rid of the mats. She loves getting her mats removed and the brushing in general. Hope that helps.

this is a question along with two possible answers, some guys choose long hair while others may prefer shorter hair

Personally I like guys with reduced hair. I don't mind it becoming a little long like 3-4 ins (maybe a little longer) as lengthy as it's styled in a great way.

i dont know what mats are, but you should ask your vet.
