Rescuekitty,you are more knowledgable than me about allergies,I don't have any allergies that I know of.As a matter of fact I've never heard of so many people being allergic to this and that as in Canada,I usually call it a Canadian desease.

Before we came to Canada I very rarely heard of anyone with allergies,but maybe it's all the pollution we now have in the air.
Maybe your cat/dog are happy outside,but I bet they would like to curl up in a warm bed with you,just like my cats do every night,that's where they belong,they are very important family members and it's a good thing we have a King-size bed or hubbie would be on the floor

Awwww Sadie,nite,nite
