Diggi, my fuzzy grey tiger cat, is an intense plant lover. I attemped to outsmart him & sprayed the leaves with tobasco sauce, but to no avail. His brother, Gizmo, learned his lesson & stayed away, but Diggi went right on munching. I also tried adding repellant cat pellets to the soil, but they didn't even slow him down. Obviously, i take care to have safe plants, but the few remaining plants i have left are sorry-looking and, as they are out of his reach, they are also lacking in adequate sunlight. I bought some cat grass to satisfy his craving, but that only increased his salad selection. My question is twofold: are there any safe plants that are naturally distasteful to cats or are there better products that will deter him from my plants (or should i simply give up & buy faux plants?!). Thanks!
