I think the *pooh* & *pee* is the Big Question that needs
an answer by morning...

He "looks" quite alert -
not what you'd think a cat in any *pain* would look like.

And if he allowed you to touch him everywhere - without showing
any discomfort or fear in his eyes...
that IS a *mystery*!

I'd suggest a "wait 'n see" till morning...
give him a blankie to sleep on;
and a litter box with a small portion of food and
a water bowl nearby;
and see how he is in the morning.

With food "on board" - he *otta* be ready to *pooh* by morning -
and for SURE by Sunday night.

If nothing "comes out" by Sunday night -
the Poor Kid NEEDS to see a Vet Monday Morning!

One word of *caution* ~
IF he has been injured - possibly a Back or Spinal injury -
he MAY *not* FEEL any pain - and that may also be why he
possibly "CAN'T" move on his own.
I'd go real *easy* on moving him around very much more -
let him move if he can - but don't "pick him up"
unless there is a serious need to do so.

Good Luck, Lil Kitty!!
