How much garlic is dangerous?

The Merck Veterinary Manual notes cats can be affected by about 5 g/kg of raw onion, or less than a teaspoon of cooked onion. Garlic is 3-5 times more toxic than onion, so the table uses the conservative 5× figure. The table shows the amount of fresh garlic reaching the 5 g/kg level. Powdered garlic is far more concentrated.

Cat weight	Fresh garlic at threshold	Roughly
6 lb	2.7 g	≈ 0.7 cloves
8 lb	3.6 g	≈ 0.9 cloves
10 lb	4.5 g	≈ 1.1 cloves
12 lb	5.4 g	≈ 1.4 cloves
14 lb	6.4 g	≈ 1.6 cloves

Smaller amounts are not "safe": effects build up over several days of exposure, and individual sensitivity varies.
