In the 70's in Hilo, I had as many as 21 cats (and 3 dogs) at one time. Over time, as many loved fur children grew old and died and I grew older I've cut down. Currently there are 5 indoor house cats (one with a daylight outdoor pass if it isn't raining), 2 shop cats (one who wants to be a house cat), one foster (whose owner recently died), one that only appears at night (took 1 year to tame and neuter, 2 years to get to friendly petting), one very old neighborhood cat with the sweetest temperament ("friendly girl").
Some recent feline friends by color scheme:
Yellow striped: Blondie, Marigold (d), Bonkers (d), Pumpkin (d); Hilo: Grundoon, Gingersnap, Banana, Ugly
