i sewed some of my panties for duchess to fit her like a gem! lol. and we put a maxi pad in them all the time. However she does have that doggie door...so we had to close that and take her out ourselfs so we could take the undies off...its not too cool when the doggy door is available...and she hops out and takes a poop in her undies! hahahaa ewwwww!
