I'm sure a big enough flap could be found. Flopsy my frenchie crossed with lionhead who weighs about 4.5kg can open our living room door :shock: She butts with her nose, then moves a step forward, butts it a bit more, steps forward etc etc until she's through. It didn't take her long to figure it out either. It always makes me laugh when I see her doing it :lol: :lol: :lol:
