Adoption event FAQ for Mount Prospect

Are there free adoption events in Mount Prospect?
Adoption events in Mount Prospect are free to attend; you pay only if you adopt. Fee-waived days remove the adoption fee entirely. Every upcoming Mount Prospect adoption event we hold is listed on this page, and adoption alerts will tell you the day a new one is added.
What is a fee-waived adoption day?
A sponsor covers the adoption fee, so the spay/neuter, vaccines and microchip it pays for cost you nothing. The application and screening are unchanged.

Yes. Most Mount Prospect adopt-a-thons bring cats and dogs, and kitten showers run through spring and summer. Each listing shows the species.
What do I need to bring to adopt a dog in Mount Prospect?
Photo ID with your Mount Prospect address, proof pets are allowed where you live, and often every member of your household. Bring a leash or carrier if you hope to go home with a pet.
How do adopt-a-thons work?
Multiple shelters and rescues gather at one venue with adoptable animals on site. You meet them, apply, and take your pet home the same day or arrange pickup.
Do I need an appointment?
Walk-ins are usual, but many shelters book the meet-and-greet by appointment. Check the organizer page linked on each Mount Prospect listing first.
Are puppies and kittens at adoption events in Mount Prospect?
Sometimes — they go fast and many live in foster homes. Kitten showers in spring are the dependable exception.
