That it's been 4 1/2 months since I got Waldo and Scooby, at which point they were supposed to be 8-10 weeks old. If the supplier was right, that makes them 6.5-7 months old, and if not, they're at least 5 months old. Neither one has shown the slightest sign of developing cresticles, so it looks like I actually have 1.4 cresties. Carmen and Sandiego are the only ones big enough to breed, but it looks like Sandiego has a future harem awaiting him. The only downside to this is that I'd really like to see what offspring from Susan and Scooby would look like, but I guess I'll have to wait for F1 to find out.
