Can a cat bath after Giardia treatment cause sneezing and pneumonia?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 5 lbs

13+y/o dil tortie SF indoor nearly 2y now tested + Giardia, vet gave me 4d Rx Panacur, after 4d: diarrhea & crying stopped. Washed her next day w/Hartz Extra Gentle Cat Shampoo bc I read to bathe after Panacur regimen to remove any contagious feces. Next day, she starts sneezing,occasional wheeze sound,&runny eyes/nose,loud breath, congested. 2d later:not eating. I syringe fed&gave sub-q fluids.Took2vet:stethoscope indicated possible pneumonia,Rx: Clavamox. Could a bath have caused this?

Hello. Unless you somehow got Noni's face underwater, there is no way bathing her caused the pneumonia. My thoughts are that her immune system has been compromised, possibly from some underlying condition. How else could she become symptomatic for Giardia while being housed strictly indoors. My thoughts are that she has always harbored this parasite ( which is not unusual ), & something triggered the Giardia to become significant. I am glad that the Panacur worked for her, but her pneumonia may be a result of something that has compromised her immune system. I would recommend chest x-rays, blood work to include testing for Feline Leukemia & Feline Immunodeficiency Disease as well as looking at her thyroid levels. I hope she is doing well soon & thanks for using Petco Pet Education Center, formerly Petcoach.
