Is this an emergency? My Mom's cat Francis has this right now. She says one pupil was dilated and the other tiny, then over time the tiny one got to normal size. She called me (yeah, I'm an expert) She says he seems fine. He's eaten, napped, wants to be pet and is grooming. I told her to call her vet to ask if this sounds serious but she says no one is available. She's afraid if she calls an ER vet that they'll say to bring him in and charge her a huge fee. Any advice? I'll try to google it too but it's a weird subject to google.
