Jax seems to be not making his jumps lately. I've never noticed him do this before.
Last night he went to jump on the back of the chair.....FAIL.
This morning he tried to jump up in the computer chair with me.....FAIL.
And just now he tried to jump on to the bathroom counter.....FAIL.

I do not see him limping or showing any pain (then again, he is a cat!).
Is this something I should worry about, or would this be considered normal?
