Hi and welcome.

You have a beautiful little girl. No idea on her age other than she’s not a baby. She may be a juvenile. I just adore female panthers and although they aren’t as showy as the males, they have their own special beauty. Most will show lovely pinks, corals, peaches or lavenders, depending on locale (which is next to impossible to determine in girls). My nosy be girl is my petite purple princess, but has also gone thru being peachy, dusky rose, tan, brown, grey, etc. Even though my girl will be 3 years old in June, she’s never laid eggs. I’ve been careful to keep her basking temp no higher than 80F and to not overfeed her…same as I do with my veiled girl. Because panthers grow so much slower than veileds though, I didn’t start to limit her feeding until she was close to about 10 months old and she was fully on ‘the regimen’ by the time she was a year old. Although I wrote this for Veileds, much of it applies to panthers too.
