I had this SAME problem with a cow, was so lost as to what to do so I googled it and this website popped up. I want to FIRST say thank-you to all of your input and say that I bought the probotics and in just 2 mornings of treatment, the third morning NO MORE SQUIRREL CHEEKS!!!! Secondly, I had called my vet BEFORE I got on this website and their answer WAS .....she had something caught in her mouth OR they would need to float her teeth. THEN I read all of your comments and FOUND MY ANSWER!!! Thank-you SO VERY MUCH for sharing because I would had lost my cow. She had gotten to where she had lost a lot of weight, was no longer feeding her calf, and the diarrhea was awful. No more hand feeding her range cubes to help her spit it out!!! I can promise you THIS, I will ALWAYS read this sight before calling my vet from now on. AGAIN, thank-you cattlemen!!!! Peteygirl
