Need help asap! My cat is sick...

[Catty1]

Can you take him to another vet for a second opinion???

[DethEna]

i did, i had 2 vets check him, give him same antibiotics, same allergy shots...They both said they can't here anything wrong with his lungs...he is having breathing problems but its because of his sneezing...i don't know what to do anymore...i've spent a lot of money already, i will get money for treatment but i don't want to keep trying without any guarantee....
