Cats are considered wild animals relative to dogs. The dna of a pet cat does not resemble difference between the dna of the wild cats. Cats act somewhat bizarre when we think about it. They are funny. They hide their poops to avoid detection. They like to sneaking in small areas. They do those things in the wild as well to hide from the dangers and hunters. Therefore, I personally choose Cats because they are interesting creatures. Desmond Morris studies about the cats are worth reading.
