I am sooo sad I have had my precious cat for 1 year now and everything seemed great. I recently acquired a kitty and it was super until it started having diarreha. This happened right after I took him to the vet for his regular check up. 5 days later my 1 year old started with diarreah as well. Mac, the older one, also started throwing up. I am very concerned. The kitty has been treated with metrano.. pill but nothing has helped. The vet wants to check to see if they have trichomonas, I was reading about this and I am so scared!! Does anybody have any advice?
