Both cats and dogs are mammals, and have various similarities despite being of separate species. This is because the two descended from the same ancestors from millions of years back. Both of these are predatory mammals, and boast of a more or less similar biology. Find out about some of the similarities or commonalities in the two species.
Both kittens and puppies begin to have solid food when they are of the same age, between the 3rd and 4th week, and this begins the weaning process. The two are weaned completely, and do not have mother’s milk any more, by the time they are 8 weeks old. The entire weaning period, for either species, might end 1 week before or last 1 week more.
The period of pregnancy, or the gestational period, happens to be quite similar in both species. The gestational period for both species lasts for around 2 months, with average dogs taking 63 days to give birth and average cats taking 65 days to reproduce. But either species normally enter labor some days later or earlier than average.
Both species like to mark their own territories. Cats mark the territory that they perceive and avoid actively crossing the boundaries of other cats unless necessary. Dogs also display a similar trait, and scare off for fight strange dogs that seem like encroaches for them. Both have the ability to hunt and scavenge.
Both of them have social habits, and like to be around others. Dogs happen to be social animals by nature and form packs in the wild to survive with companionship. Being with other dogs increases their chances of being more successful while hunting and surviving. Cats are loners but like to be with their young ones or be with other cats for mating. They also like to be showered with affection every now and then, and love to be in their own territory with a companion – even a human – for affection. It would not be wrong to say that humans enjoy a kind of symbiotic relationship with both dogs and cats, and this has been the case for millions of years.
Both species can be domesticated, breastfeed their kids, have a horizontal body structure and suffer from similar disorders such as Intestinal Parasites, ticks and fleas. There are many other similarities despite the hundreds of differences that they have with each other.
