Excess saliva a side effect of nausea medicine?

Tyson is being treated for hepatic lipidosis, and is taking Cerenia to combat the nausea associated with it. I know they drool when they are nauseas, but today he's had a lot of saliva coming out of his mouth and I don't think he's nauseas. Has anyone else experienced this either with a cat with HL, an e-tube or from nausea medicine?

He has an appointment with the vet Monday, so ill ask him too then. Just wanted to calm my nerves for now

Yes my Toby just recently drooled a lot in response to Cerenia, I have not seen this happen with him before. I thought maybe I put it in the wrong place in his mouth. I took a syringe filled with water and had him drink it, flushed his mouth and he did better. The oncologists office also mentioned that he was drooly, they said sometimes cats drool in anticipation of something bad bc they associate it with nausea.
