Small context we got my little brother a cat (I have my own doing perfectly fine) but she won’t stop having diarrhea. For context the shelter gave us medicine and said it was 7 days worth but only lasted 2 days with the dosages they told us. She had her first vet appointment and they only prescribed over the counter medicine and didn’t do any in depth testing. She is about 3 months old, we’ve tried wet food and dry food, both lead to diarrhea and it’s to the point where she dribbles out poop because she can’t hold it. I’m honestly making this post because my mom is leaning towards taking her back and even thought it’s my brothers cat I hate the idea of taking animals back to the shelter after giving them a home. Initial thought now is parasites but I just thought I’d see what the professionals/others think or may have any solutions. Trying to get ideas because it seems she may just plan on taking her back rather than getting her tested. Poor kitty is very loving she just can’t control it.
My cat’s acne has been getting worse, It started near his whiskers and migrated to his chin and it keeps getting bigger.
First vet gave me a mix of Vaseline and sugar and told me to rub his chin with it daily which I didn’t trust and when I asked for something else he gave me “miconazole 2% orange flavor” so I switched to another vet which told me to just brush it off with a flea comb and it will resolve.
It’s been over a month and I feel bad for him and I don’t know what to do
I use ceramic plates and I clean them after every meal and I make sure his water is always fresh.
I saw some people recommend vetericyn and Chlorhexidine wipes but I read that Chlorhexidine is toxic to cats so I’m not sure on what to do
