We got a Siamese kitten from a breeder and it was just diagnosed with coccidia. They prescribed medicine but from what I’m reading it can be hard to get rid of. I have 2 other cats but have been keeping the kitten quarantined in my daughters room until her tests came back which they did today. Even though we have been keeping the kitten quarantined we have been in and out of the room playing with and holding her and then playing with and holding our other cats. Please help! How can I make sure this doesn’t come back and my other cats don’t get it?? Or is it too late??
