"scout" was spayed sometime before she got here, you can still see the staple / stitch marks on her belly really well, so it couldn't have been more than 4 months ago, i'm getting her vet work tomorrow. my question is, diesel is starting his humping phase, where he's humping sheeba all the time (sheeba is spayed too). whenever he does this, scout gets upset, and barks and growls at him, shoves sheeba out the way and puts her butt in diesel's face... she gets really jealous, but only when diesel humps sheeba. diesel will NOT hump her, no matter how persistent she is. do spayed females usually do this?? she's acting like she's in heat, but she was recently spayed, could she just be acting this way because maybe she had one heat, or something?? thanks for any ideas!
