Ok, so I took my cat to the vet since she was very congested and she was sneezing a lot. The vet did a physical examination and explained to me that she may have URI so she prescribed amoxicillin and clavulanate( it's one pill) for two weeks. So I have been giving my cat the antibiotics and she is still congested. In the last two times, I gave her the medicine she threw up 1-2 hours after taking it. I have taken her into the bathroom while I run hot water in the shower so she can inhale the steam. When I tried to clean up her nose with a warm, damped cotton ball I noticed that her mucus was reddish. I called the vet and they told me to wait a little more for the antibiotics to work. Well now she's vommitting(as I mentioned above) and it's also sunday so the vet's office is closed. She's been on antibiotics for 5days now and she's stil congested. Another thing I have noticed is that when I give her treats(which are hard) she sometimes chews them and ALL the crumbs fall in the floor so she's basically eating 1/5 of her treat piece, OR she just licks the treat and looks like it hurts for her to chew on them. I am so frustrated and scared for her. Has anybody ever experienced something like this?
