Why is my cat breathing heavy, not eating, congested, and losing weight?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 8 lbs

Cat isbreathing heavy through nose, loss of appetite, not drinking a lot of water. She's using litter box, but hasn't pooped in a couple of days. I can hear what I think is congestion or phlegm when she purrs, but no sneezing or coughing. seems lethargic, but she's not that playful anyway. She's still cuddly and affectionate. She's always been vocal, but even more so now. Looks like she lost some weight and she's already tiny. I also think she has anxiety. Can you tell me what's wrong?

Shelby most likely has an upper respiratory infection or viral cold. This can cause nasal congestion and poor appetite. I recommended you take a warm cloth and clean her nose as the nasal discharge can clog up the nostrils causing the mouth breathing. Also if you warm up wet food, fish is best, it will make it more appetizing as the heat will enhance the aroma of the food. That should help to,stimulate her appetite. If Shelby isn't better soon please take her in for treatment. As she's tiny I don't want her to be sick long as she doesn't have much body reserves. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Shelby.
