Just introducing myself. I have 5 cats. I need continuous advice about my cats they have different backgrounds and different needs. My 1st is a black, polydactyl male cat from a city shelter. The next is a female, white, obese cat with FIV that used to live at a nearby abandoned house. The next 3 are kittens all from different litters. The oldest is an all white male with FIV. The next two I raised by hand.
