My cat is eating litter crystals, vomiting, and has a rash. Why?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Female | unspayed | 6 months and 3 days old | 5 lbs

My cat i rescued from outside. She had an allergy to the wet food and that was fixed and i was told she was fine! Shes now, all of a sudden got that same nasty, smelly rash however, its not due to wet food or the dry food as shes been fine with it up until a few weeks ago... now, shes eating ONLY the glade crystals from tidy cats with glade. She was throwing up alot and i didnt know why.... well, my mom caught her eating the glade crystals and sure enough, she started puking.... im scared.

Hello, and thank you for your question. I'm sorry to hear that Whiskers has been unwell. I would take away the glade crystals in the cat litter if you have not done so yet. If she is vomiting, I would recommend taking her to the vet as soon as possible to assess for any obstruction in her stomach or intestines. This can be a very serious emergency and the sooner it is addressed, the better chance we have of getting Whiskers better. Regarding the rash, sometimes food allergies can take a few weeks to manifest so it is still possible she is allergic to her current diet. I would ask your vet if they would recommend a specific hypoallergenic diet for her. I hope this helps, and that Whiskers gets the help she needs soon!
