None of my other pets seemed to notice, but my pygmy goats have. I have two does and a buck. The buck always tried to attack me before my doses were adjusted, and one of my does flirted with me A LOT. The other doe was terrified of me. After the increase in doseage, my one doe still flirts with me a lot, but the buck does too now, quite a bit. The doe that was always afraid of me is becoming less timid and occasionally approach me. They're up by the compost pile, and they regularly smell our urine (it speeds up the breakdown of compost) so they are reasonably more sensitive to my hormonal changes
