I would die of fright if someone knocked on the door.
But other than that, if all the animals remained I would have my dog Merlin to keep me company. I would probably adopt the neighbor's rhodesian ridgeback too. The other dogs in the neighborhood would probably have to take care of themselves. I would walk from house to house to make sure the pets had a way in and out of the house. I would also loot stuff I needed. Like money, jewelery, booze, tobacco and other stuff that can be used to trade with. You know, just in case aliens comes to visit me

I would have to learn how to use the manual ammunition maker in the basemant and the guns. I wouldn't step outside the house without a firearm.
My best shot at survival would be to move to the city, so I would take some time to ensure nothing bad would happen to my house while I was gone. After packing up my stuff in one of our cars I would lock the door to my house and drive to the city. Hopefully the streets aren't littered with cars. Otherwise I would have to stop the car and move all the other cars before I could keep driving.
Eventually I would arrive at the library which would be my base for the moment. I would patrol the shopping street while 'shopping' for blank journals, stationary, warm clothes, medicines, first aid-kit, soap, candy, sodas and magazines. If I find a weapon shop I would see if I could find a 9mm gun and a hunting knife. Looting the jewelry store? Yes, please

Once back at the library I would start writing a journal to keep myself from going mad, and I would start re-arranging some of the furniture. Three of the walls of the library are made of glass, so the top floor would be the best place to keep watch from.
On the second day I would drive around to search for plastic containers to store fuel in, and a trip to the furniture store would secure me a nice bed and a thick mattress. Pet stores would also be raided for dog food and toys, and small animals that wouldn't survive on their own would be put to sleep.
Once that is taken care of I live my life for as long as I can handle in hope that somehow there are other people out there, and I would write a book about myself to ensure that if humans returned in the future, I would not be forgotten.
