Please help! advice much needed! My cat is sick!

I have a 9 month year old lilac himalayan male named Suli.  From the day I brought him home he has been robust,,solid ,,full of energy ,,very curios,very vocal and always eating things he should not,,All along he has been extremely healthy but for the last two days ,abruptly he is dry heaving ,,,sneezing ,,and puking very small amounts of clear saliva, he is trying to eat and comes downstairs with my two other cats for breakfast in the morning but he seems disinterested ,,kind of the way you feel when ya have the flu,,,not wanting to eat ,,and this is unlike him. he is also very lathargec I dont know what could be wrong with him???!!!! help!!

Thanks,Ana B

i use to have a very similar kitty what love eating this she shouldn't. my best suggestion is a vet visit. It may as simple as a kitty flu and may pass, but when it comes to cats eating things they shouldn't you never want to take you time, cause it could mean a bad situation getting worse. i know my cat acted very similar to the way your describing when she ate a handful of Starburst candy wrappers out of the trash, which ended up forming a knot in her intestine and required surgery. so i'd say make a vet appointment and get little Suli in

thankyou so much! im hoping it will pass but i am scheduling an apt asap!
