Hi,I made an emergency trip to the vet last evening for cat having pretty severe lethargy and also intermittent small amounts of blood in his stool. The vet did a scan of his stomach and saw no obstructions and also did a rectal exam which was clear.He recommended doing a Cytology analysis. That's fine.he sent me home with metronidazole.I was wondering if anyone here has experience with this drug. It's in liquid form,but I am reading it can have very undesirable side effects. If anyone can help me with this I would greatly appreciate it.
