Okay first off it's not a walking jacket, it's not a jacket, it's thin. It looks like this only slightly different color. I got it at petco. That metal thing goes up, it's where you attach the leash.
Anyway I got home today, and after putting groceries away, went down and held Sabriel for a bit, petting her and such. Straight away before playing with her, before I got her too wound up, I tried the harness again. This time I listened to Brigitte's idea about distracting her with a toy afterward. Now I won't like I did get a tiny scratch on my arm that didn't bleed, and I got nipped a bit on my hands - but those didn't bleed either. She didn't nip hard. I had to take it off of her the first time I put it on because I made it too lose and she was getting the front stuck in her mouth, that's when I got the nips mostly. Then the second time I got it on her, it was still pretty loose but not too badly - so I started playing with da bird with her. She was running all over and jumping and pretty much forgot about the harness. She still let me pet her. I only kept it on her for about 20 minutes though, I want to ease her into it.
Though I am tempted to put it on her one time before bed, and make sure she can't get her mouth or something stuck on it - or be choked with it - and then let her get used to it at night... But I don't think that would be fair or nice...
So I'll slowly ease her into it.
Thing is after I took it off she was slightly afraid of me. She'd still let me play toys with her but she wouldn't let me near her to pick her up or even pet her without a toy. So I went and got her food ready and got her a few treats and she's eating now.
Tonight I'll just play her catnip mouse toys with her, and hopefully I'll get her to come couch and calm down. Well actually eating right now she's calming down. I think/hope when I go down there in a bit (like 30 minutes or so) that she'll let me pick her up again and nuzzle into her like I've been doing...
Oh also no pooh today, she had that one day last week where she had a poo incident but that was when I drastically changed her food schedule. Since then no issues and before then it'd been close to a week. I'm changing her litter box entirely tonight (I scoop it nightly), and I'm thinking of putting baking soda in there with her litter too but not sure yet.
