It dooesn't make sense...

Physiological chemistry makes sense, a lot of it. If you take a molecule and subject it to a series of reactions the end result is predictable and the same. Gluconeogenesis in a cat is no different than a dog etc.
Gross anatomy makes some sense. muscle names often help one figure out what it does (except extensor carpi ulnarus, its a weak flexor, but it's located with the extensor group). Nerves usually inervate the muscles you expect them to, bone attachments and muscle actions all have a weird logic to them.

Do you know what does not make sense? Developmental anatomy. It's weird. Everyone does it differently. some things are only true in dogs (they ovulate at a weird point in meiosis), somethings only work in primates, some stuff is the same in carnivores, primates and freaking rodents but not other animals. It makes no sense, but at 8am tomorrow I'll be tested on it.

I ask you why, in the name of everything anyone considers holy, why, does a fertilized horse ovum need to bounce around the uterus for 16 days before impanting or the mare won't recognize the pregnancy?

Cat metabolism is the one that gets me confused. Our vet has been telling us that what takes a few hours in any not cat entity will take up to two days in a cat. ((shrug))

With metabolism of many drugs/toxins it is true in cats because the lack the isoforms of a certain liver enzyme necessary to conjugate those substances and excrete them harmlessly. Theory has it that because cats are such complete carnivores they do not naturally come across many toxins so do not need to have those isoforms active. Thus drugs stay in their systems longer and smaller doses have more effect.

Is that why a cortizone shot for my cat would be effect for weeks and have no ill side effects even when the shots were given on a regular basis? The vet expained this to me years ago but I never really understood. All I knew was that the shots that made my mom miserable made my cat happy.

I'm not sure but I don't think so. The problem in the liver is with conjugating toxins and xenobiotics, but cats can conjugate steroids just fine, so i doubt it.
