I would like to thank everyone who posted, including Dr. Bruce Williams, with his wonderful clinical information. I will be cleaning again today top to bottom because Harley is coming home from the vet's after a couple of days of isolation ... they did lots of fecal samples there, I am sure!!! One thing I did not consider, and I think this is important enough to reiterate in case some people didn't read the note to me from Dr. Williams - I WAS using the same rag to clean enclosures, etc.... Now, I know that, I will throw them all out, start afresh, and ensure that they are bleached before I go to a different enclosure to clean ... nothing like defeating all my work LOL ... thanks again, Marion [Posted in FML issue 3267]
