Hi all, I am new to the Cat Site but have found the forums useful. I was wondering if anyone has any experience wit aspiration pneumonia and how it develops? For three days around a week ago. i had to give my cat Lactulose for constipation. The vet didnt tell me how to do it, so I squirted directly into her mouth. I now know that isnt the right way. Once she had a congested sounding breathing for about 5 to 10 mins after a dose. But never choking or anything. It has been a week and she has an eye flare up. I am just worried that it is an URI developing from early aspiation pneumonia?? She is otherwise okay, eating lots and pooping normally again, sleeping and cuddling a lot. Should i be worried? Does aspiration pneumonia take long to develop? I just am so concerned that by dosing her incorrectly with Lactulose I might have done serious damage to her health!
