I went through this when I first got boople. I was adamant that I would not feed in her enclosure! I got a good talking to (thanks everyone). I have a routine with boop now. She comes out, gets weighed, my son holds her while I spot clean her tank, put the rat in, then she goes back in. She knows this routine as soon as she goes on the scale. Not once has she ever bit or even struck. So honestly just feed in her enclosure.
And i thank everyone who literally put me in my place. Boop is so much happier.
