Tim above and PuddyTat below seemed unperturbed by the presence of the other critter munching catfood for breakfast.
The possum seemed unperturbed by the felines.
When I went out s/he retreated to the cardboard catbox and watched me.
When I went back in s/he checked out the other catboxes and the window. I could get nose to nose without alarming the obviously young visitor.
S/he pushed up the blanket to reveal the heating pad. I was afraid s/he would settle in between and was relieved awhile later to find my newest notcat was gone.
I don't like seeing these critters in the daylight as I worry about rabies. This young one seemed quite healthy, just hungry. I don't mind the possums because they just eat and leave. The raccoons play and do lots of damage. I won't put up with them for long before setting the trap. I never saw any critters last winter. I wouldn't be surprised to see the groundhog if we have a week of warmth.
