I'm sorry to hear this! I'm a nervous cat mom myself, so I can definitely relate. It sounds like your kitten is totally fine, though--my cat will also foam at the mouth if she tastes something unpleasant or if she has to take oral meds. She's my first cat, and I was terrified the first time it happened. I hope you can get some sleep! I'm not sleepy either, and it's 2:30am here. Going to be a long day at work tomorrow! Take care--and sorry to hear about your gallbladder--that's supposed to be a pain like no other!
