I noticed discharge from my cats eye today morning.

He acts different after other cat came from vets. Last couple of days he has been only sleeping. He eats but mostly when I offer. Not playing at all.

Other cat came from vets already 6 days ago, and her bandage was removed 4 days ago.

I have seen him shaking his front paw sometimes but he is not limping.

Can this be stress related? Is it emergency?

He is ex stray so catching him and bringing to vet is a challenge and will stress him more but possible I belive.
