My "roommate" at my parents' house is Suzy Q, a rescued feral cat.
The missing eartip is a veterinarian's mark, indicating that she has been spayed. Although you can't see it in this photo, she's also missing her tail, which was amputated some time ago because of recurring infections. She's a very small cat, about eight pounds (and, given her understandably endless enthusiasm for eating, may weigh more than that shortly...), and looks much healthier than when I first made her acquaintance.
