There's a few other general differences between estrus cycles and menstrual cycles. At ovulation, animals with an estrus cycle go into estrus, also known as "heat". During estrus, the animal is sexually receptive, and it usually isn't outside of estrus.

Okay? Okay. This is how estrus works: pre-estrus, functionally the same as the follicular phase. Again, paraphrasing. Next, the estrus phase, very similar to ovulation. Just like humans can only conceive during ovulation, these animals can only get pregnant during estrus.

After I'd already finished drawing this, I looked up how true the factoid is (I know, common folly) and apparently it's only true (from what I read) during a sheep's estrus, so they'd both have to be in estrus, but let's ignore that for this comic ^^;

Estrus cycles also frequently include a dormant phase, where the animal doesn't have a hormone cycle at all. And finally, estrus cycles tend to happen less frequently than menstruation, sometimes as infrequently as once per year.
