Also, we are going away for a few days and am having someone look after him for a few days. Can I have her crush up the Prednisolone pill and put it in Monty's food?
I think you should ask your Vet about all of these concerns. However, we do crush our cat's prednisone into her food but she is not on it for asthma. Are you currently giving the pill by mouth? Might that be why Monty is hiding under the table?
