Whew, Delia. Glad you got Cleo to the vet. Peace of mind.
She sure is a gorgeous girl. I love those colors, especially the splash of caramel on her face. A stunner.
Years ago, maybe 10 or so, my Charlie had an episode with his right pupil being dilated. Just the right. At the start of a weekend, of course. Never knew what it was. It resolved just as spontaneously as it appeared and by Monday, fine.
You've seen a vet. You'll see a specialist. Cleo is acting fine. Breathe.
And keep us posted.
Light for you both.
