I currently have dogs and have had dogs all of my life. I am well trained in behavior and at one point in my own household I had 6 animals (5 dogs ranging from 10 pounds to 100 pounds). I have not ever had dog fights in my house or houses. I feed cats and scoop boxes as well. If your cats need medications we will discuss this in person first. I have been house sitting for 8 years. I do have medical training with dogs and currently working in an Emergency Animal Hospital is anything went wrong. I am available to transport if need be. My fee does change if you have over 4 pets, the rate changes to $10/pet per night. For example I recently sat for a house with 8 pets so I charged $80/per night.
