I'm watching documentary about vet. And I can't understand meaning of 'draining' in these conversations.
- One person brought their cat to doctor. She said this about cat's eye.
It was all puffed up, and then the next morning it was draining blood.
Does this mean cat was bleeding through eye? or it became red? or became pale?
- Doctor looked into Dog's eye and said "draining eye"
Does this mean eye became red or dry?
