Like mentioned, they dont feed love, hate, jealousy etc but i do think they feel security and do retain knowledge of their owner through familiarity. When i took my beardie to the vet the first time, she was terrorfied of the vet and pooped on her and then leaped on the exam table and then onto me and ran up my shirt and hide under my chin. My big girl Rosey when she went to the vet, she spent the whole time trying to get back to me. The vet and nurse had a time holding her down lol. Finally the vet just let her sit on me while she did what part of the exam she could as Rosey was quiet and curious on me but off me, she did nothing but try and get back to me.
And i swear Rosey and Gina actually seem to enjoy coming out to wander around or sit on me. Probably just me projecting the feeling but sometimes when i open Rosey's door, she is more than happy to climb out onto me for a ride. Caesar also seems to enjoy interacting with me but he isnt a big fan of being dragged around for me the most part lol.
