My leopard won't touch dried grasses or even freshly cut grass unless he grazes himself, so a great tip I was given by someone here was to grind the grass/hay up in a blender to almost a powder and sprinkle it on wet food he does like ( dandies, Florette crispy salad in my torts case), spray the grass again and mix in. Its a good sneaky way of getting the grass/hay into him I use Readigrass ,but don't know of you can get that in USA
