As the gap between the door grills is wide enough for a home cat to venture out, the guardians hit upon the idea of putting up mop-sticks between the grills. Alternately is to split a clothes-hanging bamboo stick into 4 and insert between the grills. The bamboo sticks would be taller and hence there would not be a need for wire-mesh at the base even but the mop-sticks are aesthetically more acceptable.
