i am a retired large animal vet and my house cat is experiencing an acute episode of asthma. we are treating her with pred 5 mg bid and theophylline 25 mg bid but she is still very wheezy and lethargic. i have a nebulizor and inhalation solution of albuterol + ipratropium. consulted with cat's regular vet and we can not find any dosage or recommendation of the ipratropium. would assume since it is an atropine compound would be safe, any one have any experience in this area?

also would appreciate any suggestions for long term therapy, it's very difficult to jump species after years of cows and horses and i admit to not being very objective when it comes to this special cat

thanks susan
