My first rat was a true shoulder rat. I could take her outside and never worry. I never thought about rat leashes then because she didnt need one. She use to walk around the block with me and there were never any issues. I let her roam anywhere in my house because all I had to do if I lost where she was was call her name and she'd come running. I miss that. She passed away sometime ago and I feel like my other rats just aren't getting this shoulder rat thing. I think part of the problem is I unfortunately had to leave them with my dad for a couple months when I first moved for my new job and I dont think he took them out of their cage often enough. I feel like during the time they spent apart from me they forgot all their previous training. For example before leaving them my oldest three came to their names, they werent' at the point when I would dare trust them outside but since I got them back they sort of pick and choose when they are going to respond to their names. It drives me crazy. I cant really trust them to do much of anything on their own because I never know when they are going to come when I call and when they are going to ignore me when I call. My other rat is technically still considered a baby, well maybe a toddler by now I guess but I understand why she isnt getting the shoulder rat thing since shes still young and we haven't done enough training but I dont get why my older girls were becoming shoulder rats and now just dont care. I feel like leaving them for those two months was such a big mistake. Even though I cant take back those months before is there any hope these girls can ever be trusted to come to their names 100% of the time and maybe eventually be trusted to go outside? I feel like I was so blessed with my first rat like she was a super smart girl without me even having to try. I dont expect my new girls to be an exact replica of her, but Id love if they could at least somewhat listen as well as she did. Do you think part of it's a trust issue because I abandoned them for a couple months there? I really didnt want to but there was no other way. It makes me so mad now though that they use to listen and now just dont care. I literally dont know what to do.
