Is the spay and neuter clinic walk up service? Or do you make an appointment? The answering machine message is a little confusing.

Appointments are for surgeries only. The afternoon clinic is not for surgeries.

Walk-up only. But it really doesn't take long

If you leave a message on the answering machine someone will call you back.

Currently, Everyone lines up outside. They help you in order. No Appointment. You can call when they are open and pre-checkin. Then when you arrive you'd wait in the pre-checkin line.

Its walk up 1:00 to 4:00 Monday through Friday I think not sure about Monday I usually go on Saturday
