As some of you might remember, Nepo's been an outside bunny for the past 2 years. I feel really bad for him since it gets really hot outside during the summer and even with a fan and a frozen water bottle, he still can't be as comfortable as possible. Plus I think he gets really lonely and I miss him being inside the house :( . So today I was thinking of getting him used to being inside the house so that when it's really hot he'll come inside :) so I brought him inside and let him run around the house (the first 10 minutes he wouldn't move because he was a little scared, but after that he started hopping around the house for about 5 minutes) but as soon as I opened the door that goes outside, he got out, ran a little bit, and went in his cage. I know at this point he likes it more outside, but do you guys think he could learn to like the house again?? I plan on bringing him inside tomorrow for like 10 or 15 minutes... I don't know if I'm doing this right tho...

Be careful cause a 20° temperature change could actually kill him.
