I think to make it valid, your second premise would need to be "Only animals have eyes". The statement "All animals have eyes" allows that there could be something that has eyes that is not an animal, so it does not require the conclusion tht all people are animals.

You can be cruel to animals without you knowing. Unfortunately the subject gets clouded because people tend to anthropomorphise.

How do you test an enthymeme for validity?
Although there is some disagreement about the precise rules for a valid syllogism --particularly about the "existential" requirement -- there is general agreement on some tests. To test the validity of an enthymeme, fill in the missing premise, then examine the premises and the conclusion. Max Black (Critical Thinking) listed eight rules for a valid syllogism. Irving Copi (Introduction to Logic) reduced them to six:1. It must have three, and only three, unambiguous categorical terms.2. The middle term must be distributed at least once.3. If either the major or the minor term is distributed in the premises, it must be distributed in the conclusion.4. Two negative premises yield no valid conclusion.5. If one of the premises is negative, then the conclusion must be negative.6. Two particular premises yield no valid conclusion.

It is invalid because: Think of it like a fried egg. The white being striped animals and the yolk being all zebras. The yolk is in the middle of the white. Well, polar bears can be in the white without being in the yolk. Polar bears can also be half in the white and half on your plate. Therefore, Some polar bears maybe striped animals.
