The prednisolone is liquid, just use a syringe and squirt it into her mouth. The one our vet has is chicken and bacon flavored which she tolerates pretty well. We actually just restarted it since her asthma was getting bad again, and we’re going to titrate to as low of a dose as is effective since there are some downsides with long-term pred use. She’ll generally have a vet visit once or twice a year to reevaluate

Ours has been managed with fluticasone HFA (just increased to 200mcg yesterday) and a low oral dose of prednisolone daily. Sorry your cat is having such a rough time :(
