Ah he has more legs in those pics
! His face is just the sweetest, cutest thing ... look at those eyes!!
Yeah the mail you the papers later thing is normal as far as I know ... will be interesting to see if they do show up!
January 8th is the date of birth of my Maine Coon kitten that I am waiting on (he was supposed to arrive this weekend but had some neutering issues so I have another couple of weeks to wait!)! I definitely don't believe your kitten was born then though. My bengal kitten was 11 weeks old when I got her and her eyes were a gold-yellow then ... they will eventually be green. Mika was fuzzy at 11 weeks but nowhere near as fuzzy as she was at eight weeks - at eight weeks her fuzzies made her spots much blurrier and her overall coat colour seemed a much paler shade. Mia was 2.4 pounds at 10 weeks so your kitten would be awfully small weight wise for 12 weeks.
Do check your kitten out in the sunlight for glitter as has already been suggested ... not all Bengals have glitter but I believe the majority do ... you'll know it when you see it, it looks like gold ... glitter
... usually easier to see along their backs, but Mika has glitter on her nose and toes in some lights too.
I'm so glad you've decided to keep him and help him recover!
