i have been having a huge lack of rainbow boxes, i was breeding 16 prs, and getting 2-5 rainbow boxes per breeding cycle, which for me was 5 days cuz i used meds on the kitties. Now 3 cycles have gone by, i have 10 breeding pairs and have had 2 boxes......... from 3 cycles, i am so sad i have some great traits that are just going to die out
