Despite not being humans, we often see our fuzzy friends as members of our family and household, who live under one roof, sharing good times and bad. So it shouldn’t come as a surprise to anyone that some of our pets might start to act like the other animals in the home are basically their family as well.
People from across the internet share funny, cute, and adorable photos of pet pairs, from actual siblings to interspecies found-families. So get comfortable as you scroll through, upvote your favorites, and be sure to share your own thoughts and experiences in the comments section below. We also got in touch with Nina Thompson from the San Diego Humane Society to learn more.
