Why Dogs and Cats Can’t Mate?

Dogs and cats are different species, which means they have different numbers of chromosomes. Chromosomes are structures in cells that carry genetic information. Dogs have 39 pairs of chromosomes, while cats have 19 pairs. This difference in chromosome number means that dogs and cats cannot produce viable offspring.

Even if a dog and a cat could mate, their reproductive systems are not compatible. Dogs have a bulbus glandis, a structure at the base of their penis that swells during mating to prevent them from withdrawing. Cats, on the other hand, have a barbed penis that stimulates ovulation in the female. These differences in reproductive anatomy make it impossible for dogs and cats to mate successfully.

Risks of Interspecies Mating

Even if a dog and a cat could mate, it would not be advisable. Interspecies mating can be dangerous for both animals involved. There is a risk of injury during mating due to the differences in size and anatomy between dogs and cats. Additionally, if a dog were to mount a cat, there is a risk of transmitting diseases and infections between the two animals.


In conclusion, dogs and cats cannot mate and produce offspring. Their reproductive systems are not compatible, and even if they were, it would not be advisable due to the risks involved. If you have both a dog and a cat as pets, it is important to keep them separated to prevent any unwanted mating attempts.
