Often times, volunteering for a cat rescue organization is not all fun with kittens.
Feral cats are trapped, then TNR'd, which is the best outcome for some felines.

Barn cats need to learn where home is; they need to have warm dry shelter, fed regularly, and have protections from pedators.
They are typically housed in a secure location (barn, large kennel) for 4-6 weeks. This gives them time to acclimate and transition to their new 'home'.
I only had a short time with Keegan, but she was the sweetest kitten. Have good life Keegan!
She was adopted! Congrats little girl!
