If it were possible to mix a cat and a dog, I'm sure you'd see them all over, but there are several barriers, prezygotic (before the egg) and post-zygotic (after the egg) to whether or not an animal can reproduce with another animal. They are:

Prezygotic barriers can either cause difficulty in mating or prevent/hinder the fertilization of ova if members of different species attempt to mate. These barriers include the following:

A) Habitat isolation – this example involve the rare, chance encounter that two species may have if they live in different habitats but are not separated by geographical isolation (ex: two species of garter snake that are in the same genus live in the same area, but one species lives mainly in water while the other remains on land).

B) Behavioral isolation – Special signals or unique behaviors used to attract mates are the most important reproductive barriers among closely related animals. (ex: courtship rituals between two closely related species of birds)

C) Temporal isolation – This occurs when closely related species mate at different times of the year (ex: two species of skunks that overlap in range but one mates in late summer and the other in late winter; plants that flower on different days)

D) Mechanical isolation – anatomical incompatibility

E) Gametic isolation – zygotes cannot form after sperm and egg meet. The sperm will very rarely fuse with the egg probably because of recognition components on the egg that will only accept a certain sperm.

Postzygotic barriers occur after fusing of the egg with the sperm but barriers exist after fertilization to prevent development into a viable and fertile adult. Some examples of these types of barriers are as follows:

A) Reduced hybrid viability – genetic incompatibility

B) Reduced hybrid fertility – hybrids are usually infertile (horse and donkey mate but produce sterile mule so genes are not passed onto the next generation)

C) Hybrid breakdown – this involves reduced viability or fertility of offspring. The first generation of offspring may be fine but continued mating results in the offspring being very fragile.

Sure, IF you have them taxidermied together after they die. Have you heard of the hairy trout some guy supposedly fished out of a lake? Well, he was making them in his basement!!

But in reality, NO. And a cat and dog would have absolutely no interest in mating with each other to begin with.
