Wow! Guess what?! I decided that inside isn't the bad place I thought it was. Being inside for a day changed my mind, even though I hated the trap and hated that I was inside when it was happening. Now that I've had a couple days to think it over, though, I'm finding it very interesting.
Today, I decided that I wanted to check it out more. When the daddy opened the door for my sister, I was right there. The daddy left the door open a little for me to socialize with the inside cats. Freya was busy grooming my sister, because she kind of thinks my sister is her own kitten. I could tell my sister was happy, so I looked at the door, then looked at the daddy and meowed. He opened the door a little more, and I walked through!
I went to the food bowl first and sniffed it, then sniffed the water bowl. I walked back out the door, and the daddy called to the mommy to come see me. She watched from the hallway and he watched from the living room as I came back inside and sniffed the bowls again. Then I walked into the kitchen, still crouching low because I was unsure what was going to happen. My sister wanted to come see me, so she hopped down from her spot on the blanket-covered table. That sound scared me, though, and I ran back outside!
A little later, I went back over to the now-semi-closed door. Heimdall had his head out the door, sniffing the outside air, so I walked along the wall until I got to the door (just in case he was going to come outside). He turned toward me and we touched noses!
