After about 2-3 months, we can see that the cat's testicles have emerged.

However, it's important to note that around 6 months of age, a kitten's testicles should be easily visible and palpable. If you can't see or feel them, you should consider the possibility of cryptorchidism. If you're still unsure, it's recommended to take your kitten to a veterinary clinic promptly to avoid impacting its health.
