Hmmm. It's kind of hard to tell from the picture...but if I had to guess...well, it looks like possibly...Opal? But it almost looks like it has bands of darker colour down it's back... Looks agouti, also... hmm.
Possibly Lynx? Do you have belly and ring color shots? (I know the ring color won't be well defined at this age, but we might be able to see a little definition). What color are the eyes?
