I think it should be done more often. I know that whenever I foster a kitty and find a "forever" home for them, I always tell the new parents to please send me pictures so I can see how they are doing. I do get phone calls once in a while or I'll call the home just to say hi, how's it going. So far I have had only good things said. It pays to check up. But like Sammi said, most times it's due to short staff and budget cuts.
