I was watching my Rhino eat when all of a sundan he started shaking his head violtinly ( he was not choking ) and starting trashing his legs to the side . then he ran to the other side of the cage sliding to a stop with his eyes caved in ,and his tail flickering . I though he died . He's done that three times in the last couple hous . His vet is 1 1/2 south and no way in can get him in until tomorrow . If anything happens to him i am done . i have put too much time into him and not going to start over . Its just to heart wrenching
