I noticed my female mojave females lip looked odd last night. Opened her mouth up and noticed the overall color of the mouth was greyish in color not bright pink. Their is also a black spot in the very front of the mouth. Has anyone had this happen and what do I do ? My temps were slightly low due to a cold winter and my humidity is a lot higher than normal could this be what caused this issue ? Also anyone know of a good vet in Southern California ? Thanks.
