How long will it take for Henry to feel better?

Henry became poorly on Monday, he started being very lethargic and just not wanting to do much. We took him to the vet yesterday where he was diagnosed with swollen glands, a sore throat and a fever/a viral infection.

He was given an injection of convenia and meloxicam, this morning he was being sick so we took him again to make sure nothing was wrong and he was given another injection of cerenia to stop him from being sick.

I'm just wondering if anybody knows how long it will take for him to feel better? we hate seeing him like this!#

-Next stop will be back to the vet for blood tests!

I am surprised the vet didn't already do blood tests when Henry was there. Nobody can know when he will fell better, but we hope it will be soon.

Yes, it certainly depends on what's wrong with him when he'll feel better.  He is dehydrated?  Did the Vet give you any "after care" instructions?

that Henry feels better soon!
