3 years ago, we had to put my cat, Sophie, to sleep. We knew something was wrong with her, but we didn't know what.
My mom would babysit these twins whose mom worked in a vet's office. She volunteered to take Sophie up to see the vet (We couldn't afford to take her ourselves). Later, my mom called her to see how everything was going, but she told us that Sophie was too sick and had to be put down.
