41Gryphon -- Well, I hope you can find a solution where you don't regret it.
When you find the right solution you'll know it's right in your heart. You'll probably always miss her, but if you find the right home or another solution, hopefully you shouldn't feel regret.
Maybe seek out a home with someone who's willing to keep in touch and provide an occasional photo, video, and note?
I know that helps many people find peace of mind. I offer that for all of the animals I adopt because I KNOW how hard it is to rehome an animal.
And I post updates on my bird site that a couple former owners peek in regularly. And I keep in touch with a number of people who adopted foster birds (and cats and dogs) from me.
It sounds like you're seeking a permanent home for Dakota. But I did want to mention that some people offer long-term foster homes.
They're rather hard to find but they do exist.
I offer this myself. I've kept birds, dogs, cats and even ferrets for people who needed a home for their pet anywhere from a few months to a couple years.
Most of the owners have been military people who didn't want to give away their pets due to deployment. I've had owners who had a 6-month deployment and others who had several deployments over the course of a couple years.
But I've also had other situations, like a woman who needed open heart surgery and knew she'd be facing months of recovery. But she couldn't afford boarding, didn't have any family who could take the bird. So I took her for 5 months while she had her surgery and recovered.
Long-term foster homes are hard to find but they do exist.
I imagine it would be tough for you since you're looking at finding a home for 3 years of high school, plus 4 years of college. And even then you may not be ready to take her back since you don't know where you'll be in 7 years.
But that's how long-term foster homes work. Every long term foster that I take in, I'm prepared to keep them for the rest of their life if need be. I've taken in a couple dozen long-term fosters and all but two took the animal back (and in one case, it was because the cat passed away.)
If you do do a long-term fostering arrangement, make sure you get something in writing. If it's something that interests you, I can send you the agreement that I utilize.
You're not traveling to Florida any time in the near future are you?
If so, I'm dead serious when I say I'll take her in a heartbeat!
