Hairs are delicate and need frequent treatment and grooming, otherwise you end up with big messy hair unable to care for them by your self. For sure you know that hairs get matted if you don’t groom there every day.
Meeting one of the cats was a total shock for the relative that entered the house. Her fur was so matted, that resembled dreadlocks. For sure she had been neglected for years, cause there is no other explanation for her condition.
