If it helps my Wilbur was 8 months when i got her and a robo. She would scream at me or run and hide from me.Within 2/3 weeks she was jumping on my hand. She absolutely loves coming out now usually 3 times a day as i can't resist her gorgeous face
Mabel i rescued at 12 months and have had her around 3 weeks now she is also a robo and is a such a little sweetie. Its like she appreciates being loved.
Rescuing is so rewarding and if you have the space and time i say go for it, you wont regret it
Though i'm warning you, rescuing can become rather addictive!!
