This is a Fundraiser for the CPHS Fur Babies! The CPHS is NOT a Retail Outlet for Puppie Love or Kittie Kittie T- Shirts. Once we place the order on the 15th of Every Month, it will likely take 7-10 business days for you to receive your shirts depending on availability from Maryland Brand the t-shirt company. All net proceeds (approximately 1/2 of every t-shirt) goes to help the CPHS animals with Meds and Vet Bills. We are sorry we cannot exchange sizes. Many Tail Wags in Thanks from our Fur Babies!
