Should penalties for crimes against pets & animals by humans be more harsh?

(From change.org) We ask for the penalties given to animal abusers begin with a minimum and mandatory sentence of six years and then to include more time at the judge’s discretion.
We ask that once an abuser is convicted of animal cruelty they are not allowed to have a pet for the rest of their lives and must register on a registry for animal abusers.. It is well documented that animal abusers are more likely to abuse or kill people.
We are asking that any crime against companion animals be classified as a felony.
In the laws against animal cruelty we ask to be included bestiality, tethering of any kind in a truck bed or any part of a vehicle, tied up outside for more than an hour a day. Guardians cannot crop a dog’s ears. Dogs and cats must not be left outside or in a garage or dog house or any other unheated area when it is below 50 degrees. Dogs and cats must not be left out in the rain or snow or be made to live in conditions that are muddy or cluttered. Animals must not be left in an enclosure where they cannot stretch, walk around or get fresh air for an extended period of time or be without any human contact for extended periods of time. Dog collars must not be too tight; they should be two fingers in width between the dog’s neck and the collar to ensure it does not cause neck lacerations on the dog. Animals cannot be used in rituals where animals are abused or sacrificed. Dogs and cats must not be hindered from moving around in what is natural and healthy to the animal, and must not be forced into a painful and dangerous situation.
We ask that a guardian of animal immediately lose all rights to any dog or cat found to be starving or dehydrated on their property. To have to get the guardian’s permission to relinquish the animal only prolongs getting help for the victim.
Cruelty is defined as an animal put or forced into a situation that causes harm or is not natural.
