Garlic is very toxic to both cats and dogs. Obviously depends on the size of the beast but it's more concentrated than onion so takes less to do damage.I've done the following, all with no problem:
- Tablespoon of Parmesan cheese per batch.
- Teaspoon granulated or powdered garlic per batch.
- Food coloring (yellow for "chicken", red for "beef"). Takes much more food coloring than you would think, but it works.
