That's definitely something I feel like I've noticed, Oz seemed to do better after the emergency vet fluids and after the primary vet fluids. I'm hoping fluids today will help too
She still hasn't eaten today and also has no interest in the baby food. It looks very like nausea to me, moving away from offered food and lip-licking. I'm worried the phos-bind upset her stomach, I will need to be more careful about it being given with a meal but I didn't expect her to refuse food this morning. It's also not going to be super effective today with no food to bind to phosphates from.
She can have another dose of her nausea med in about two and a half hours, hopefully that helps.
