hi all i finally found out why my barnaby was having trouble breathing! he is allergic to the white pine in the barn dry pellets i was using. and with in 2 days after removing the pine pellets his nose cleared up. i'm switching over to mountain fresh pet litter < the pellet co. that makes it has stated that the difference between mountain fresh and the other pellets is these are heated to over 400' degrees which removes the impurities and any toxins that are in the wood. my barny is doing well and will be off the antibiotics by Friday. rich samantha & barnaby & the ghost of pogo [Posted in FML issue 3957]
