Hi, today we are draining a large dermal cyst on a cat. First thing you do is give him lots of love and tell him everything will be okay. Then we isolate the cyst with rubbing alcohol. We've washed our hands so there's no need to waste PPE. Then we insert a large needle in and make sure to express out all the contents. Sys are not infected, but you do need to make sure to surgically remove them to avoid them from coming back. He's not a great surgical candidate, so this is what's making him most comfortable, so we do it as needed.
