Please Answer question about my cat

My cat bootsy just had 4 healthy kittens on new years eve. Shes been fine since, other then this evening shes started to swallow frequently almost like shes going to puke but doesnt..her puring also sounds different if anyone may know anything please help! Shes happy and fine other wise .

Is she eating and drinking OK? Can you open her mouth without causing stress? She may have got something caught in her mouth or throat. If it goes on more than a few hours I would take her to the vet.

Yes she is drinking and eating really good and if it keeps happening i will take her in tomorrow... She seems better as of now (maybe im just being extra paranoid) bec she just had kittens??? Idk lol
