Perfectly fine.
My cat had the same tooth removal surgery a couple years ago (he was adopted with a mouth full of teeth where most were about to fall out). He was on soft food for about 2-3 weeks before he started picking at his dry food again. Now he gets a portion of wet food every morning, and free feeds dry all day.
What I learned from the vet is that cats use their teeth mainly to rip meat off their prey so they can swallow it, and not really to chew. So if they’re presented with food that’s an appropriate size to swallow, they just swallow it.
I’ve had bad experiences with melatonin, but now I find it can be helpful in smaller doses. I cycle through a bedtime thc/CBD/melatonin sleep aid (Wonder Wellness Sleep), L-theanine, and melatonin, only taking one for tops a week at a time. That rotation seems to help.
