I am dutch but I will type this in English for anyone to read. 

The experience I have is with cats, dogs, rats, hamsters, snails and fish. This includes knowledge on how these animals behave when they are ill and what to do in these situations. My knowledge comes from the experiences I have had with my own pets and growing up with pets all of my life. My cats went through two surgeries that required them to be in a bench for 6 weeks and I remember how difficult it was to balance this with my work and school. Aditionally (unfortunately), I have experience with a cat that had Ataxia and could not take care of herself properly. She was required to be held stable when eating and help going to the litter box etc.

I'm able to read and understand the behavior of these animals to know when they are uncomfortable or when I am crossing their boundaries. Especially when it comes to cats or rats or any rodents I know to be patient, gentle and to not push myself onto them if they do not wish. I have experience with pets and specifically cats that are anxious and skittish. I also have experience with cats that don't like people :P.

When walking dogs I think it is important to go on a long walk at least once a day, for my families dog this was at least an hour and a half, and then a regular walk (30 mins) so they can pee, poo and smell around. Obviously, this will depend on the type of dog and the age of the dog.

My main motivators are that I love animals, I would love to have more pets myself and immediately my second point: I do not have the financial means or space. To get a small amount of money and get to know more animals in my life would be a great pleasure. I think I can provide a great service in the same way that I wish people would take care of my beloved pets. 

I know how difficult it is to trust someone watching your pets but I pay attention to great detail and I will make sure your animals will be happy and feel loved. 

I am open to watching your regular pet but am very open to pets such as ferrets, bunnies, birds, reptiles etc although my experience does not go as far: I am kind, gentle and patient with animals.
