Poor baby! Do put a bowl of fresh water nearby. She should begin drinking soon as her thirst cues begin to kick in as more of the residual anesthesia wears off.
Adding to the cause of infection - her missed antibiotic from day one and two definitely played a role.Update after her first review: turns out that the sutures did get wet when she sat in that water puddle. They had come loose under the bandage and there was an infection. Her temperature was high too. She went through more trauma in the hospital today, thrashing and crying while the IV was put in. They put her under sedation, debrided the incision and restitched her.
8 hours later, she's still partly zoned out - but woke up when I waved food in front of her nose.
