YEAP
Lexi just finished her heat cycle.
I didn't let them mate this time.
Scruffy started smelling her & humping her about 1 wk before she came into heat.
He marks all over the house at this time.
I use Belly Bands on him when the girls are in Heat.
The girls use a diaper.
Plus it is double protection when I don't want them mate.
I bought mine from YT member Tiger's Mom at go fetch
