I watch a webcam at Friends of Felines Rescue Center in Ohio. (
www.ffrc.petfinder.com is their website) At any point in time, they house 60-100 (approx) cats. In the main portion of the center, are some resident cats, mainly geriatric cats, but there are a couple that are younger, and the cats that are available for adoption. There is a staff of approximately 40 volunteers that work in 3 shifts throughout the day, 7 days a week. Each shift, they feed, clean boxes, mop, brush all the long hair and medium hair kitties, do laundry, change towels and pillow cases off of perches and beds, and a host of other things. All of the cats live in harmony together; it's amazing. There are the occasional squabbles, but no serious fights. Each morning, Jacci (the founder) checks her book of kitties to see who needs vaccines, nail trims, flea treatments, or other medication. She weighs kittens and cats that have medical issues and records all that. There is a low-cost clinic on the premises and 3X a week a vet comes to do spays, neuters, and wellness checks for the kitties at the shelter and in the community.
There are also cats who live on the sunporch. They couldn't handle living indoors for whatever reason (spraying, fighting, and etc.) In the winter, they are moved into the big barn that is totally equipped with heat, weatherproof, and they have all the ammenities of home. During the summer months, they have enclosed areas in which to live. They also are tended to during the 3 shifts.
The last group of cats are the Cat's Cove cats. These are mostly former ferals who have behavior problems, medical issues, or some other situation that makes them unadoptable. They live in the big barn that has rugs on the floor, lots of cat furniture for them to lay/jump on, and cat walkways all around. They are also part of the 3 shifts and are loved on, fed, groomed, etc daily.
I'm not exactly sure how big all of FFRC is, but I do know that it's all volunteer and run on a lot of donations. They just built a new addition to the Center to serve as an isolation area for new intakes and for those recovering from surgery or new moms and kittens. Every single cat is vetted, de-wormed, flea treated, and very loved.
