From my copy of someone's extracted world.dat raws, some beast syndrome effects have SIZE_DILUTES or/and SIZE_DELAYS. These tags will (respectively) reduce the severity of an effect and delay the effect based on either the amount of material the creature comes in contact with or the size of the creature, or both. According to the wiki this hasn't really been tested yet, or at least the tests can't be verified to be reliable and accurate, but if that information is at least partially correct, then it would imply that cats could be vastly more susceptable to a toxin, because of their small size, than other creatures would.
The cat may experience (far more severe) symptoms within a matter of days, but a dog could live months without feeling ill. Dwarves and anything bigger that could have been exposed would last even longer before succumbing. All depending on how the SIZE_DELAYS tag's hardcoded equation works. Hell, an elephant or larger may have a teeny-tiny chance to live long enough the effect ends and the
survive, but may also go about their business for several years before showing symptoms.
[Edit:] I can confirm that the SIZE_DELAYS token works to some degree, as a creature of size 5,000 will be affected sooner than one of 500,000. I also did it with another of size 50,000,000, but I can't tell if there was a delay between it and the 500,000 group (I could try again with my FPS cap lowered, though. It's at 300 currently.) They also survived the syndrome.

Tiny horses will always die sooner than normal horses, which will always die sooner than giant horses (which will not die...) after being gassed by the titan I copied, unless the SIZE_DELAYS tag is removed. The syndrome was modified for the purpose of testing the SIZE_DELAYS tag, and the bleeding symptom was used.
Technically they'll still die (or not) in that order, but it's obvious they
start bleeding at the same time. They just die in order of who has the most/least blood to lose.
Only really reliable method of delivery I found is a trailing vapor flow, so i can't guarantee that extract sample size from the gassing is the same, and thus I can't really test the SIZE_DILUTES token.
