This is my Eastern Garter snake. I dont know how how old she is. How am I able to tell. Sorry about the water spots. Its from misting or pour water on her, which she loves both. She is pregnant but I dont know how far along. Shes a little over 3 foot long and because shes pregnant shes about the size around of a 50 cent peice. Shes gonna shed again in the next day or 2 . Her eyes were fogged for about 3 days and they cleared up today. Like I said Id like to know how Im sopposed to tell how old she is. Oh, along both sides of the center stripe on her back is skinny red lines. They look soo much wider now beacause of pregnancy. How long are they pregnant for and how do they act right before having babies. She has gotten more aggressive for a little over 2 weeks now maybe a cpl days longer. Anything that you can tell me will be awesome. Thank you all and Im glad I found these forums cause everyone is soo nice. Thanks all.
