Maybe there is hope to find my cat?

So - long story short. I found my kitten right after thanksgiving. I took it in and provided care. I was trying to get its vaccination and microchip…however I had a last minute trip to Europe (and that region). I left the cat in my place in care of my brother…in a couple of days my brother said the cat ran off outside and he couldn’t find it. Rightfully so I was pissed - I got back Sunday night and I talked to one of my neighbors who said they saw a kitten and took it to the SPCA. I contacted the SPCA and they said the kitten matching the description was adopted roughly two days after it was brought in. So - now I’m sitting here hoping I can find a way to catch up with them and offer to pay whatever they paid for the kitten or even pay for a new kitten for them from the SPCA. Idk I can work out the things. But she is a cute kitten that for the first time made me want to keep a cat :,). Shooting my shot on Reddit - but if I can’t find my way back to her then it was honestly meant to be.
