So... I called the vet and everything should be okay...
The funny thing was that we had guests over on Sunday for a BBQ and Max somehow managed to get Mikki out of her diapers and they tied again...
Imagine my hubby holding the two horny teenagers in his arms and I'm trying to get Max' swelling down with ice cubes so they can 'untie'... Our guests were literally laughing tears and assured us that we really do everything to entertain them...
Of course nobody had a camera handy...
