My kitten is lethargic and not eating after deworming. Is this normal?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 2 months and 8 days old | 3 lbs

My 66 days old kitten just went through deworming. She is now secluding herself and just lying on my bed. She is barely eating. (Last ate at 8 pm and as of writing this it will have been 21 hours since then) and had some diluted milk in the morning. about hours prior. She isn't eating any food offered to her nor drinking anything. She salivated twice for less than 15 minutes each time about 9 hours apart. She had diarrhea last night and also didn't threw up on the night of the deworming. Help?

Thank you for submitting your question regarding Penny. I recommend that she sees a veterinarian today. I worry that she will become dehydrated from not eating well and losing fluid in the diarrhea. The veterinarian will examine her and determine if she would benefit from fluids under her skin and possibly anti-nausea medication. Deworming medication can make a kitten sick if she had a high worm burden. As the parasites die off, the kitten can become ill. I hope this information helps!
