How long for wet tail antibiotics to work?

[Lemon]

Update: I visited her today

She had energy to walk around for 10 minutes but then got tired and went to sleep. Poor baby looked like a bit heavier of breathing than usual while sleeping so of course I’m worried she got tired so fast

Idk if she was awake already before I got there. She’s still staying with the vet

She’s been eating and drinking tiny bits by herself

But I’m still so worried about how tired she was so fast
