My 9-month-old cat is throwing up worms. Are Zentel & Maxolon safe?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 9 months and 12 days old

Cat started throwing up last night - yellow vomit with long thin worms (roundworms?) in it. Thews up about once every 5 hours. He hasn't been eating since yesterday, over 24 hours; ate boiled chicken once last night but threw up soon after. I have been told to give him: - Zentel 2 ml, once a day - Maxolon syrup 1 ml, morning and evening Are Zentel and Maxolon ok for a 9 month old? How do I give him the med? He's refusing to eat food so I can't mix them with meal. Thanks.

Maloxon is to stop the vomiting, Zental is a type of dewormer which i would probably not recommend to use if you have a better alternative (drontal, Milbemax, Profender). if yu have no other alternative you can use both medications, the zentel needs to be given only for 3 days.
