<human>: Condense the text into a few key points

Hello doggit! I grew up with dogs at my dad's house and cats at my mom's house, but have never had both at once. I recently got a cat and obviously have no idea what I'm doing. Please help!

**Cat:** Unnamed, so we'll just call him "Cat". He is an almost-fully-grown kitten. As of right now, he hates dogs and is especially terrified of my big dog. 

**Dog:** Callie is a little over a year old, 55lbs, and extremely rambunctious. She just wants to play and doesn't realize how big she is or how rough she plays. She is normally very well behaved, but gets SUPER excited when she sees Cat, and all her training goes out the door. 

Normally I think I'd just let them work it out but I'm not entirely sure Callie won't kill him. Though her body language is playful for now, I worry prey drive could kick in.

I have a really small apartment and future plan for the kitty (once he's neutered and up to date on all his shots) to be a mostly outdoor cat, and to give him a cat door so he can come in and out freely. But right now he has to be an inside cat, so I just keep them totally separated with him in my bedroom and her in the living room. 

Yesterday I put Cat in an extra large dog crate and then let my dog sniff at him from the outside. At first he was terrified but then started to calm down once he realized she couldn't get to him. She obsessed for hours and wouldn't leave him alone, and whined and barked because she was so frustrated. I have also tried holding him while she sniffs, but she gets so excited she just wants to jump and completely forgets all her training. Then Cat starts clawing me. 

What should I do? Should I just continue what I'm doing and hope that Callie stops being so excited as time passes? Should I let the cat and Callie run around together while Callie is on a leash? Or have any other suggestions?
<bot>: Got a cat who hates dogs, have a dog who is so excited by cats that she forgets all her training. How do I ensure they become friends with minimum stress (and without dog killing cat)?
