How do I get stains (cat fur balls) out of my leather chairs?

Best to get the mess off when the mess is still fresh, wipe with paper towels. You can use leather polish on the chairs if needed.

What kind of leather is it raw,napped,finished?what color? if it has eaten thru the dye & finish you cannot probably fix it well all you can do is clean it up(start with itty bit of dawn dish soap and good scrub maybe even gently brushing depending on leather finish blotting and rinse as you go)--nap or not and try to redye the area to match if the finish has been colored from acid in stomach fluid or food dyes in it. the stomach acids are tough on anything they sit on especially leather and wood furniture.This product is really good to use on any leathers https://buyleatherhoney.com/landing/leather-cleaner-google-us/?gclid=EAIaIQobChMInqHCzsiy5AIVaB-tBh3ukQ3TEAAYASAAEgJmxvD_BwE here is more info. https://mycarneedsthis.com/best-leather-conditioner-and-cleaners-to-buy/ many of the cleaners/conditioners might darken it. more helpful stuff https://leatherworldtech.com/custom-leather-vinyl-recoloring-kit/?_vsrefdom=adwords&gclid=EAIaIQobChMIsejMkMuy5AIVEiCtBh39KgWwEAQYBSABEgJLL_D_BwE

If its stained and you can't get it out, you could re-stain the whole couch a darker color with analine dye from leathertouchup.com They are on YouTube with videos showing how to.

Then give kitty some of the fur ball gel daily, use 1/2" of the stuff from the tube.... my cats like the salmon flavor and the malt flavor.
