My cat's sebaceous cyst just burst and a cheesy like glop came out. My vet said this would happen but I don't remember what I should do to care for it now that it's drained and she has a hole in her skin. No blood or pain isassociated

You can apply a warm and damp washcloth to the area, which will help the area continue to drain. Gently trim back Hocus's fur, and clean the area with antiseptic soap. I would not put any antibiotic cream on it. Although quite safe on superficial wounds, cats groom and ingest most of the topical ointment you apply and therefore should be used only under direct veterinary supervision and if there are no other appropriate options. Many human ointments contain multiple other ingredients which are not necessarily safe to be swallowed. I would keep an Ecollar on Hocus to keep her from licking at it, and keep her indoors if she is allowed outside. Monitor the hole for signs of infection, which include redness, swelling, warmth to the touch, and pus. Should you see any of those signs, I would take her into the vet as she will need antibiotics to treat the infection.
