Our fees are always waived on all working cats.

Puppies and kittens must be at least 8-weeks old and weigh 2 pounds for surgery. We do not spay or neuter animals more than 8-years old without recent blood work. We will spay or neuter pets that are in heat.

General volunteers must be at least 16-years old, but kids 12 through 15 can participate in our Junior Volunteer Club.

When you adopt a pet, please bring:

• A valid photo ID with your current address. If your ID does not have your current address, please bring another type of proof, such a utility bill, water bill or vehicle registration.
• Family members needed to finalize the adoption. If a dog-dog visit is necessary due to an animal’s history, your adoption counselor will advise you.

A working cat (sometimes called a mouser or a barn cat) is one with a history and temperament better suited to an outdoor lifestyle. These cats may live in a barn, stable or other outdoor setting where they have a “job” and a better quality of life.

All adoptions include:

• Spay or neuter surgeries
• Age-appropriate vaccinations
• A microchip ID
• A free wellness visit with a participating veterinarian.
• A temporary collar and ID tag
• A temporary leash or a carrier

Currently, classes are available for:

• Bully prevention
• Dumb Friends League 101

And so many more! Check out our complete list of classes today.
