Oh absolutely. Energy does not end. My sweet Kumu, a shih tzu, still greets me at the door when I come home. Not everyday, but often. He has been gone for 5 years now. I know when I cross over, he will be there to great me with my grandparents and others who are on the other side.
I also know they are all going to be there today for our little cat, who is going to cross over today. I know she will be loved and someone will pet her under her chin and Kumu will play with her and she will be very happy.
Energy does not end, it continues with all that it is. We are not this body, we are the energy of the Universe. We continue on and on.
