Our cats love playing with frogs as soon as the rain comes they are out in the garden frog hunting. as soon as they catch one they bring it in to play with. usually the frog gets rescued much to the cats dissaprovment, the frog will get put back in the garden but occasionally one gets under furniture ,ie, the bed or wardrobe where the cats cannot get under, and the result is a dead petrified frog as long as the frog has not been injured it will not decompose thus leaving a bad smell in the house,
