My kitten is sick after medication. What do I do if the vet is closed?

I am afraid this is an emergency. You will need to take your kitten to a veterinarian out of hours clinic now. Ivory could have an intestinal obstruction having ingested a toy or other foreign body. The fact that he feels cold to touch is also a serious concern. Please take Ivory to a vet now.

Your cat really needs to see a vet if he has been vomiting for hours. I would see if there is an ER clinic in your area you can take him into now. If not, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Please find an ER vet or a vet on call to see him now. Until them, withhold food and offer water. Keep him warm and comfortable.

Please contact your vet clinic immediately to confirm what treatments had been gievn - these are not normal signs and are very concerning. I am not familiar with any 'anti drug' and would advise a full review of her history as soon as possible. You may request a consult here or seek referral to an internal medicine specialist to discuss in more detail

Oh poor Phoenix! Given that he is still vomiting without it stopping, it's time to see emergency care. He will need a shot to stop the vomit, which the vet can give him. I would take him into an ER vet or find a vet on call to see him now.

I think you can safely wait until morning unless the clinical signs seem to persist or get worse. Small cats can definitely dehydrate or become hypoglycemic rather quickly, so persistent vomiting and diarrhea can become a problem. I would also consider separate the sick kitten from the healthy two until you have become certain that there is no infectious or contagious disease. Hope this helps!

Besides making sure that the kitten is eating and drinking there is not much more you can do without veterinary care. Monitor for additional signs and have the kitten examined by a vet if he becomes worse. He may need an oral antibiotic and/or other medications to help treat. You could also try a Lysine supplement and see if that helps.

You cannot do anything at this time. Cats cannot really take over the counter medications and especially not a kitten this small. She really needs a vet ASAP so I would suggest an emergency clinic. That is your only option other than just waiting (which I don't recommend). If she was an adult, waiting might be OK.
