Tell hubby it's a good thing the bandage is off--keeping dermatitis from breathing leads to nasties...
How miserable is she in the collar? Our dogs all initially act like the world is ending
, but by the end of the first few hours, they pretty much accept it. Using the litter box might be a problem if she's digging the litter up trying to sniff it...since we only have dogs I don't have any advice for you there, except maybe taking it off when she has to go. The problem with that is that if she's unwilling to let you put it back on, it might lead to frequent struggles...
Otherwise, she should do okay with drinking and eating as long as the bowls are put on the floor. You might have to guide the edge of her cone the first few times till she figures out how to position herself to get in the bowls.
She'll do good. In a few days, she'll have it off and be back to normal!
And in a week or so, you'll both have forgotten what a pain the Dreaded Elizabethan Collar can be.
