My cat has a URI and is on amoxicillin. Why is her mouth open while sleeping?

Poor Cece, it does sound like she has an Upper respiratory tract infection. This could be viral and therefore there is not a lot we tend to prescribe in terms of medications, as the body will fight the infection in 7-10 days. You just need to make sure she is kept indoors and clean her nose/eyes regularly if getting crusty, encourage her to eat with strong smelling food, like fish for example, if she is not eating her normal diet. Hope this helps !

It can take several days for an antibiotic to take effect against a bacterial infection, but not all upper respiratory infections are bacterial in origin. Many are actually viral which will have to run their course with supportive care. The drooling and foaming at the mouth can sometimes be seen shortly after administering oral medications such as Clavamox since they taste badly to cats. Matted fur could be caused by not feeling well enough to groom. Not eating is common in cats that can't smell well since they are smell-driven when eating. I would recommend that you try to give Sam water or pedialyte to stay hydrated, and try "smelly" cat food such as canned cat food or canned tuna. If he isn't better tomorrow, becomes profoundly lethargic, or you cannot get food or water into him, then he should be re-evaluated by your vet for other treatment options or even hospitalization.

Thank you for submitting your question regarding Pou. Drooling is typically the result of nausea, oral pain or ingesting something with a bad taste. He will need to see his veterinarian if his symptoms persist. If he did acquire the respiratory infection from his housemate, then post-nasal drop could be making him nauseous. I hope this information helps!

Hello, sorry to hear about Tig. You can try to wipe his nose often and make sure the air is humidified majority of the time. Most often the signs can last up to 5 days and then improve. In regards to the drooling, yes Doxycycline may cause nausea and vomitng which can present as excessive drooling. Additionally in cats, doxycycline can cause esophageal changes, so make sure when administering this medication you are chasing it with plenty of water. Give him the medications before or after a large meal to limit his GI signs. Hope this helps and best of luck.

This does appear to be a normal reaction to oral medication. Cats really do not like the taste of the medication and tend to drool and hold their mouth open. If this was to happen 20 minutes, or more after you gave the medication, then I'd be concerned that it is an adverse reaction to the medication. In that case, it would be best to contact your veterinarian. If the medication appears to be stressing her out so much that she is having labored breathing, then it may be worthwhile to change the way it is delivered. Your veterinarian can advise more about this. It would be good to take a video of what you are seeing after giving the medication. You can show this to your vet and they can help determine how serious this is. I hope that helps and Sofi gets better soon.

While I think it is probably a reaction to the medication I don't necessarily think that it is a 'bad' reaction. Some cats react to the flavor of antibiotics or become stressed when the medication is administered which leads to drooling. This antibiotic could also cause nausea, but if Dusky isn't vomiting the drooling probably isn't related to nausea. You could try giving the antibiotic right after a meal to hopefully minimize any chance of nausea.

This can be from pain or nausea from the medicine and excessive drooling that can along with oral pain. You can try to feed a sensitive stomach food or talk to your vet about adding nausea medication tohim
