The Montgomery County SPCA is holding its Spay Day for cats on Saturday, Oct. 17 at its Perkiomenville shelter. Spay Day happens three times a year at the location.

This spay event is only for domestic cats, not feral cats, the SPCA said. Appointments must be made in advance by calling 610-754-7822. There is a limited number of cats that can be spayed on Saturday. Cost is $20 for males, $25 for females and must be paid by cash or check.

All cats brought in must have been inoculated for rabies and must be in a cat carrier. A towel must be inside the carrier for the cat, and the carrier should have the owner's name, address and phone number on it.

Cats that are registered should be brought in to the shelter between 8:30 and 9 a.m. on Saturday. They should have no water and food after midnight Friday.

All money raised goes back to help the SPCA with its shelters.

A future spay day for dogs is being considered.
