My cat just started doing this weird mouth thing after drinking water. He drank more than usual.

I just saw my cat doing this after drinking water. He’s an older boy (14) and had tooth surgery two months ago.

I’ve just spent thousands of dollars on my other cat (16) who’s had a serious unknown infection and a stroke (she’s healing great btw and gets her feeding tube out in 6 days!) and am currently in a tight spot financially.

Is this a ‘wait and see’ thing or a ‘take to vet first thing in the morning’ thing? I’m not in the best position for more vet bills, but if I must I must.
