WENT TO TELL VET THE CORTISONE PILLS DID NOT WORK ON MY CAT.... AFTER A COUPLE OF MONTHS SHE STILL HAS THE ASTHMA ATTACKS.... VET SUGGESTED AN EXPLORATORY PROCEEDURE ( 450$$$) AND I SUGGESTED DIFFERENT MEDS.... I GOT AN ANTIBIOTIC AND A MED FOR LUNGWORM.... WE WILL SEE HOW SHE IS IN 2 WEEKS... IF BETTER I GET MORE LUNGWORM MEDS TO KILL THE NEW HATCHED WORMS... AND IF NOT BETTER I GUESS I WILL HAVE TO DO THE EXPLORATORY TEST....
