Cats do well in the cold with their fur if they can stay dry and be away from biting winds. Well, there are some cat condos out back and the side door of the garage is propped open to provide shelter. The bride spent $12 grand several years back to have the garage rebuilt and it's solid for shelter.
It's important for a feral cat to be loaded up with good food and carry some fat to burn during cold weather and I do my best to make that happen. I laid out warm water, kibble, platters of premium wet cat food and cans of "human food" tuna and sardines for the cats after the 9th race at Aqueduct became official.
