cats

I'm not too informed on that, but that table looks sensible as long as you keep in mind that their diet is mostly meat-based, so watch out for amounts. And it fits well what I've read across the internet.

The main problem regarding dairy is the lactose; it isn't poisonous but they don't digest it well. So dairy in small amounts as a treat is probably fine, just don't overdo it. Soured milk is probably better than plain milk, as the souring likely consumes some of the lactose. Or yoghurt, one of my cats is crazy for that.

Past that, as a general rule:

• OK: gourds (pumpkin, cucumber, watermelon)
• OK: apple, banana
• never OK: alium (onion, leek, garlic) is outright poisonous
• treat it as "not OK" by default: other botanical fruits, unless you know that it's OK
• OK, but don't overdo it: non-meat animal protein (cheese, eggs)
• probably OK in small bits, don't overdo it: if it has too much sugar, salt, or fat (ice cream, peanut butter)
• not OK: if it could give you food poisoning (raw chicken)
• not OK: if it could mechanically harm you once chewed (chicken bones)
