Welcome! Pigs are very often missexed, which is why there are so many accidental pregnancies. I'm glad you did some research before adopting them and took them to a vet. There's no definitive way to tell a pig's age, but things like nails and teeth can sometimes give a general idea.

Definitely check out the stickies here and read up on proper diet and care. You will probably want a top on your cage since you have cats (even if they seem fine with the pigs).
