Capetonians Against Animal Abuse (CAAA), does not have a physical shelter and is totally reliant upon foster parents, to nurture and care for rescues. They can only save, what they have foster homes for.
I share this information on fostering with you, because it is by far the most satisfying experience I have encountered. Once you get past the initial doubts, it becomes so easy to do. Foster care frees up space in a shelter or rescue, allowing them to save another cat. Some cats do not adjust well in the shelter environment due to health issues or being too small, and those ones need fostering.
