Last night I go out to lock up and my snuggly silkie roo did not make it up the ladder. He actually look like he was twisting his neck around. I put him on the ramp and he stepped sideways. He's 2 years old. I actually went out with a flashlight at midnight to check on him. This morning he acted fine like the rest of them. I'm relieved. Of course he's my snuggle muffin!
