Uber-Dilated Cats Eyes

My cat Midnight came in this afternoon when I got home from work, ate her afternoon treat of lactose-reduced cat's milk, and went straight to sleep, not bothering to go back outside.  Normally she goes right back out after being fed, which I assumed she did.  I found her hours later asleep in my room.  She finally rose, and I discovered she was favoring her right foreleg, and was lethargic.  I felt her for injuries and found none apparent, but it caught me odd that she allowed me to so easily grope her--she doesn't like to be picked up or touched unless SHE initiates it.  She was seemingly too weak to fight me, or knew I was trying to help.  I'm worried about her and am playing the waiting game to see how she fares thru the night, but now I just noticed her pupils are EXTREMELY dilated, regardless of light variation. Is this dilation a sign of fear, due to pain, or could it be something worse, like a kitty concussion? Or after reading other posts, rabies? (DOUBLE the dilation shown in the attached photo.)

Maybe, it's not as serious as it seems!  It might be an infection from getting bitten by another cat.  I would take her to the vet to make sure.  They will pobably shave her paw to see what's going on with it.

The dilated eyes, could possibly be from pain.  I have read that pain will cause the pupils to dilate.

Take her to a vet. It could be a sign of concussion.
