@Teocato: we give them two or three meals a day and bring them to the vet (if we get them, of course) in case of need. Outdoor cats spend the winter under a little roof: the white "thing" they are laying on, is my heater; we have also provided them a kennel.
@what's new pussy-cat: yes, we have five indoor cats (Sheherazade, Liquirizia, Scarface, Sandokan, Fragola), four outdoor cats (Balin, Bianchino, MiaoMix, Scolorina) and a few more cats who drop by occasionally.
