Hi,
Im new to snake keeping (but have kept lizards all my life) so am a bit inexperienced handling snakes. I got a new california king snake a few days ago which is about 8 or 9 months old. The first few days he was great to take out of of the viv and handle was extremely relaxed and placid. But the last day or two, any time I go pick him up he starts immediately rattling his tail and goes into the S position ready to strike and will not let me pick him up. Any help or suggestion would be greatly appreciated.
