If you take in more than six companion animals per year, or three and three unweaned litters then after January 1, 2003, you must register with the State Veterinarian (SV) as a 'Companion Animal Rescue Agency' (CARA). If a CARA uses foster homes, those foster homes must also be registered with the SV unless they take only two or fewer dogs per year.
CARAs must be open to the public during 'reasonable hours.' Since this is similar to the wording used for pounds, ('reasonable hours during the week') this looks like a requirement for a schedule of hours when the private home is open to walk-in visitors. Does this mean that private home owners are expected to open their homes to unscreened strangers during business hours? Only by appointment? Does it mean you can't say 'No' if someone nasty wants to come?
It is certainly true that CARAs can go "underground"---I imagine many of them will. But why should they have to do that?
