Help, have ?. I have a Very petite Siamese mix (wast old lynx). She still has fangs (baby teeth), Vet wants to pull, have to get her to gain weight so have been force feeding a prescription food besides her regular food. Hasn't gained weight in two months. Today went to brush teeth, the one he said had to be pulled is gone, she cried when I went ti brush. Will take back to vet. Wanted to know if anyone has ever heard of this? MIA has always been a freak, doesn't meow, except if wants me and door is shut. Has had other weird things wrong since 4 weeks old. Only 6 pounds.
