Take ur cat to the vet, if theres not enough time give ur cat some water so it can go down, pat oon ur cats back to make it spit it out.Thats all i know if ti helped rate me please.
I suppose your best bet would be the same as you do with a child, hold the dog upside down and give a few firm slaps between the shoulder blades and see if that dislodges it.
If you get food stuck in your throat just get some coca-cola and it should break down the food and you will eventually swallow it. If food is stuck for longer than 20 minutes go to the emergency room.
