Videos of any pet are great and can bring happiness to thousands. YouTube is a great place to post the actual video.
If you want to talk about a cute cat video (or any other pet's video) then you can post an article here and include a link to the YouTube video if appropriate.
Pets bring us happiness through the companionship they provide but also through their peculiar humorous behaviors. Hence YouTube cat videos go viral.
A dog or cat are the obvious choice for a pet. But our family actually chose a bird (parakeet), which soon became two birds so the first one wouldn't get lonely; that quickly turned into seven (the original two liked each other a lot and had clutches).
Yes our birds bred multiple times and each time we had willing friends who thought the parakeets were so cute that they accepted one or more as a gift. But soon we ran out of friends who wanted parakeets so now we have the original pair and two of their female offspring.
The original pair were a turquoise female and an olive to light green colored male. In the various clutches (hatched eggs numbering between 2 and 5) there have always been green and purple feathered baby birds. Currently the two baby birds we kept are purple and sunlight green. We love all four of our birds but now we've learned to keep them all separate to avoid expanding from our current group of four.
A parakeet's ability to amuse was surprising. These birds have been called the "clowns" of the bird kingdom and that's not only because of their bright coloring. These little guys will act up.
Oliver, the original male bird loves to walk on the inside roof of his cage even when his cage door is open and he could easily fly around the room instead of expending the effort to hang upside down inside of his cage, or walk across the roof of it claw over claw in "hand over hand" manner. For some reason this behavior is humorous to watch.
Cricket, the original female has a little bird playground that she can perch on, swing on, or climb on (they all can use the playground). For some reason she prefers perching on the living room lampshade instead of on any wooden or rope perch on the playground. Both the playground and lampshade are next to the window so she is not choosing sunlight as a preference. In fact she seems to know that perching on the lampshade is a no-no because as soon as you take two steps toward her she flies immediately over to a perch on the playground. When you turn away from her she'll fly back to the lampshade. This "little dance" will go on until she is placed back into her cage for safe keeping.
There is more to say about our other birds but I won't go into the antics of Kobe (our purple bird) or Sunshine (the light yellow one). The behavior of pets have a surprising way of lifting our spirits. If you are not a pet person you may be able to get the same effect by watching the antics of other people's pets on their posted YouTube videos.
