Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Mint! Yes, it is possible that Mint is sick. She could have a fever. Causes for lethargic kittens are: fever from viral infections which can be GI or upper respiratory. There are more serious viral infections like panleukopenia, feline leukemia, feline immunodeficiency virus, feline infectious peritonitis. She could be nauseous from eating something she shouldn't have or from worms or she ate something that is stuck. I recommend you have your Vet examine her if she doesn't start to perk up. I wouldn't wait more than 36-48 hours. I hope this helps and I wish Mint a speedy recovery!
