I have two Nigerian pygmies (Luke and Leia) that I've had for about two months. (Their now about four months) Both have had cocci. The vet told me when I treated leia, that it was because I was probably not keeping them clean...but I clean their barn at least every other day. Their water is fresh everyday, and they eat out of a raised feeder... Luke got it about a month later. Is there something else that could be causing it?? Have any of you had these problems??
