I know they sometimes have specials where it is $5 or free. Your best bet would be to stop by and ask, or call them. Thank you for planning ahead for your pet!
First thank you for caring enough to microchip your cat. I know that it is $25.00 to spay or neuter a cat so it would be less then that. Probably $10.00-$15.00. Call the shelter for an exact cost.
