A Veterans Day Adoption Special

This Veterans Day week, we’re honoring those who serve with an adoption promotion! Adoption fees will be waived on all adult pets 1 year and older from November 5, 2026, to November 12, 2026, for Veterans, Active Military, and Gold Star Families.

Double the squeaks, double the love! Our Small, But Mighty promotion continues through our Veterans Day adoption promotion. Adopt one guinea pig and welcome home a second of the same sex at no additional adoption fee.
