Why is my cat eating and drinking excessively after being sick?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 1 year and 4 months old | 5 lbs

my cat threw up 5 times and wasn't eating for 3 days so we took her to the vet and they gave us syringes for feeding and now she's eating and drinking on her own but way too much I'm talking like eating and drinking portions every hour or 3 hours I'm afraid she might have hypothyroidism

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your question. I would recommend having her blood tested to ensure there are no abnormalities such as thyroid disease or diabetes. I would speak with the veterinarian again and see if you can bring her in to have her blood drawn and tested to rule out other causes. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
