Cat takes too long to recover after neutering

Ok, guys, I'm new here, and I'd really appreciate any help I can get.

Just a few words of introduction:I've lived with cats since I was born (that's 40+ years) and consider them to be dearest beings good Lord placed on this world.Also, English is not my native language, so if some of my sentences seem unusual or offensive, I assure you, it was not intentional.
My backyard is surrounded with wire fence and it's sort of really big, big cage and all my cats live there, safe.All my male cats are neutered, and the procedure has always went pretty easy, within 48 hours the cat would completely recover.
So, here is the thing: Mr.V was neutered about 8 days ago, he did seem to took longer time to recover, but eventually started eating.He's always been a picky eater, not the kind of cat that would come running at the sound of food, and took his time with his meals.But prior to neutering, he's been a very energetic cat, would run around the yard and house.Around fourth day after procedure, he started sneezing, there is neglible amount of clear discharge from his nose, and very slight amount of clear discharge form his left eye.He is eating and drinking water, but he just doesn't seem like himself, he sleeps a lot and seems a bit off?
I called the vet, and he said that anesthesia is really stressful for cats, and that this should resolve with time.He also said that if cat should develop fever, stop eating or drinking, or the discharge from his nose and eyes would no longer be clear, we should bring him there.

So, should I wait for few more days, or take Mr.V to another vet?

Thank you all for taking time to read my post and especially to those that answer.

I would look for another vet.   Just to be sure.  He should have bounced back by now, and even though the discharge is clear, you could have an infection in the early stages.  By eight days, he should be back to normal.

Your English is excellent.  We have members all over the world and are very accustomed to the little quirks of usage from those for whom English is a second language.  Just adds character, so far as we are concerned!    Welcome to The Cat Site!  And please, let us know what the vet says about Mr. V.

I would take him to another vet, nasal and eye discharge is not normal. I agree with the vet as far as the anesthesia being very stressful, but that unfortunately also means he could have caught something from a sick cat (at home or at the vet) since stress weakens the immune system. It could be nothing serious, or it could be the start of an upper respiratory infection. It could also be coincidence, and has nothing to do with the stress of being neutered and something is blooming or he got exposed to something that he is slightly allergic to. I'd rather just get him checked out and be safe then sorry.

Thanks to all for replying.

I spoke with another vet, and she told me basically the same thing as the first one.

Luckily, Mr.V woke up much happier this morning, was even running quite a bit around the house and jumped in my arms, there is no more discharge from nose or eye, and he sneezed only once, so I guess it really just takes longer time for some cats.He's still not completely his former self, but he's getting much better.

I'll keep this thread updated with his progress, and Mr.V waves his paw meowing "hello". :-)

Thanks.

Give Mr. V a chin skritch for me, and tell him my Hekitty sends a headbonk and purrs.
