Dumping cats... You can only see two heads because the third cat is tucked-in pretty tight. They are probably close relatives or even littermates; these now-grown orange tabby cats stick together, which is a good thing.
The orange trend in this particular feral colony started a few years ago with a cat that was probably dumped. I'm sure it was former pet because it was friendly.
I live in a rural area near dairy farms; which is why I have access to so many feral cats in case you wondered. Many of the cats in these colonies, however, are regular housecats. People often dump cats when they become inconvenient. They probably choose a farm area because they believe some myth about cats having great lives on farms.
People think (or want to believe) "Oh, a dairy farm. Lots of milk, the kitty will be fine. Just fine..."
Well, this is the post where I tell you the sad truth. That whole "dairy" thing is just a myth, my friends. The truth is that a modern commercial dairy is a terrible place for a cat - especially a house cat that has never lived outdoors. This isn't the 19th century! Modern commercial dairies are mechanized, stainless steel-lined factory operations. Hardly a drop of milk is spilled and what does find its way into the stainless steel run-off gutters is heavily contaminated with cleaning fluids and other chemicals. No milk for kitty.
Instead, what your pet will find is an inhospitable climate and a colony of very hungry cats competing for the one and only resource the commercial dairy offers: field mice.
If your cat is not a top-notch hunter, it will slowly starve to death. If it is a hunter, it has a chance. There aren't enough mice to go around, however, so even a good hunter will find itself constantly on the edge of starvation.
That dairy doesn't sound so great after all, does it? It isn't....
