Need Help with Pets

So, i bought a Pet at outpost with the Purchaseable Pets mod. After placing the pet house i demolished it and placed it somewere, where i thought it would be more fitting. As it turns out suddenly there was another Pet. After a restart of the Game there were still two Pets.
My question is, who to 'Delete' them. If you know anything about simmiliar incidents, Please Tell me.
Thanks in Advance
