Looks like I spoke too soon. Baby attacked Zoë and I ran her to the vet. Zoë was howling and crying the entire way there. There was so much blood I was certain that Baby had severed an artery or something.
Turns out Zoë is just a huge drama queen. Baby bit her ear and she was bleeding from there but nothing else. All the way to the vet for nothing, they must think I am crazy. I think a lot of blood came from Baby. It looks like Zoë must have gotten Baby back. She had blood on her face, her nose, and in her mouth.
All of this on a day where I feel like crap. Thanks girls.
