Is the fur kind of dry looking? greasy looking? or shiny and silky?
Plenty of water in your cats diet?
Dry food or wet being fed?
Wink had awful matted, dry fur when he was unregulated. He did not feel well enough to groom himself, especially around his hip area. Once he started eating wet food instead of dry, he perked up, started pulling the mats out with his teeth, stopped have frequent UTI's and his fur is now shiny and silky.
I think the increased water content in the canned food made a major difference in how he felt.
