Looks really good! It's unusual they didn't shave her. Watch for spreading redness, swelling, and a thick-colored discharge, which means it is infected. slight swelling, a little redness, and a watery discharge is normal. Looks normal!
Wow! She grew back her fur quickly! Almost always, i go by how a cat is acting to discover any illnesses or injuries. if the cat is acting normal, eating, drinking, and using the litter box, everything is fine......
