"Not one of the above characteristics have been proven and two of them, feelings and love their families is completely subjective even in humans."
Scientists have found that animals are sentient and animals do feel suffering. However, even before this we could know this, just like we do know that we are sentient and the persons we are communicating with are sentient.
I don't understand why you are arguing this.
I do know that you didn't want to transport the dog you took care of from USA to Israel because that you loved him and you didn't want him to suffer and die. You do believe the dog you took care of was sentient and had the ability to suffer. You also wrote in another post that you are for some kind of supervision of animal treatment; and this is obviously because that you do believe that animals are sentient and have the ability to suffer.
You do not need science in order to understand that animals are sentient and that animals are suffering. Anyone having a close relationship to some animal understands this.
If you just extended your love and compassion to all other animals, you would become a vegan.
Animals love for their family:

If you also watch the videos on www.vegankit.com you will also learn that animals don’t want to die.
"“Thanksgiving dinner's sad and thankless. Christmas dinner's dark and blue. When you stop and try to see it From the turkey's point of view. Sunday dinner isn't sunny. Easter feasts are just bad luck. When you see it from the vieoint of a chicken or a duck. Oh how I once loved tuna salad Pork and lobsters, lamb chops too Till I stopped and looked at dinner From the dinner's point of view.”
