I'm looking to clarify the UV questions. My BT has a UV Fluro and Calcium with D3, but everyone will tell you that "It's good to take them outside", etc. My queries:
1. If the only place you can take them in a given moment is a yard that is open to the sky directly above but is receiving no sun because you are in the shadow of the house (&/or surrounding houses) or because it is an overcast day, is that of much benefit? And is it also about checking the weather UV index (like right now is evidently 2) and a really low index is next to useless?
2. If you could take them for a stroll and there is even perhaps sun on them, but it is cold (air and ground) because it is Autumn or Winter, is the cold (& the shock of going from the warmth to the cold) worse for them than the sun is beneficial?
I'm just talking UV here, not the benefits of a stroll on morale. He can stroll around the house (where it's warmer) and explore (both my yards are boring too and the backyard is just concrete).
Thanks guys!
