I grew up with cats. I remember crying for a whole day when we put our first cat down after 18 years. My family has had 4 cats total. In college, I decided to get a dog. Who knows why, but I did it. I love my dog to death, (except when he barks constantly)! I like animals for the most part to preface my next statement.
So, a wise friend of mine once said, "What is even more mystifying is when people have animals, and they don’t have a real residence of their own." I completely agree with this statement. If you are transient so to speak, why would you subject an animal to that unstable life? Furthermore, if you can barely support yourself, then why on earth would you take on another living being to support? It's not fair to others, yourself, or the animal! Lastly, if you don't really like your animal, let your animal in your room, or care to spend time with your animal, then why do you have it?! There are loving people in the world that would love to take care of an uncared for pet.
