noodles are ok, nothing poisonous. Many cats fancy to eat a little of most human food, even fruits and groceries. No harm as long as it isnt theirs main food.
Choklad is no good!!! dangerous.
Of course, cats are carnivores, this means the main part of their food should be animal products of different sorts.
But to eat some is not dangerous. Possibly not giving them anything good, but not dangerous as such.
(OK, some cats cants stands quick changes in diet, but...).
There are some warnings:
Choklad no good no. RED varning!
many cats dont copy laktose, ie milk sugar. Therefore they get diarrea of the common milk. but all milk products (dairy?) is ok, and lowlactose milk with reduced halt of lactose is ok. Or simple water!
But if they did drink milk and fanced it and were OK - it is harmless for them. Some copy, others not.
Much liver is not good, as much of A-vitamin is no good.
But other animal products and biproducts as heart is excellent.
Cats usually love tuna, but much tuna is not good - unless you dont add extra e-vitamin.
Much raw fish is not good (destroys B-vitamins).
Raw white of eggs not so good, but yellow of eggs (yolk) excellent.
If you give them much meat (pure muscles) you must give extra calcium too in some form.
Edit. Right, garlic and onions may be poisonous. But luck cats usually dont fancy it.
Thats is about all.
So, they may try with almost everything human food as long it is fresh, save choklad - poisonous. And perhaps milk.
