A boy named Sue just happened to us! We chose a cat from SIL's litter, and she's an adorable cream/pale orange that I named Theodora Corduroy.
After taking her to the vet at 7 weeks for an eye infection, we were informed Theodora was a boy. We now have Theodore Corduroy :-). The vet wasn't even 100 percent because of Theo's age, but he was right! Theo's now 8-1/2 weeks and definitely a boy.
