Unfortunately, cat items cannot be returned. If you're purchasing a Walking Jacket or harness, please measure your cat with a tape measure before you buy! International Customers: You will receive an email from USPS when I purchase your shipping label. Once they leave the US, packages are almost impossible to track, and I cannot be responsible for packages that are "stuck" somewhere between my post office and yours. Be sure to check customs charges before you buy because I fill out customs forms accurately and honestly.
