Phish is gorgeous!
It sure sounds to me like the cats are living in the barn and using it for shelter. If you don't want the cats euthanized, please do not call animal control! If you tell us where you live - State works, but including your city is even better - we can help you search for resources - local groups to help. You can also search on your own, using the links in my signature line (below). Rescue Resources will help you locate either trap-neuter-return groups that can help, or a local no-kill shelter.
Just beware that most no-kill shelters are full, especially now during kitten season. Many will take in feral cats, but if they are not social, the ferals will be euthanized, even though they call themselves a no-kill shelter.
If you love cats as much as we do, you may want to become their caretaker. Unfortunately, if all you do is feed them, they will multiply, and rapidly. In order for them to live out their natural lives without the group of cats growing, you must have them all spayed and neutered.
Kittens are usually easily adopted out, either through a local vet or shelter. But it is safe to spay and neuter cats as young as seven weeks old.
If you decide to take on the project yourself, you can learn a lot about "trap-neuter-return" and how it works at www.alleycat.org
, and www.straypetadvocacy.org
We can help you each step along the way. It may take some time to trap and have all the cats sterilized, but they can become wonderful "outdoor" pets over time, and without the ability to reproduce, the colony will gradually diminish as the cats live out their lives.
With a barn, it may not hurt to have a few cats as "mousers." We've been able to place many ferals from unwanted properties on properties with barns specifically because of that. We were able to trap and have spayed/neutered 28 cats on the property here two years ago. All the kittens were adopted out (save those we adopted ourselves
), and since then all the feral adults have been placed in area barns.
If you need help searching for resources or with information on how to find a trap and have them fixed on your own, just let us know!
