My cat isn’t well

Hi guys,

My cat since two days is hiding and not eating well.

I took her to the vet. Her temperature was high and they gave her antibiotics and fluid.

She is still not well. I am waiting for the blood test and urine test and X-ray.

She is indoor cat. She doesn’t go out. No change in the environment.

What could be happening with her ??

She is Scottish fold 1.5 years
