Make a grumpy cat happy

I grew up in a house with cats and dogs, my mother has 2 cats (Shoby and Pisu) and 1 dog (Minie) and my sister has a dog (Shiba). When I was younger, my sister and I liked to rescue animals on the streets. I was a scout girl and I taught the kids to respect and love the nature and the animals. When my friends and family go on vacation, I am the first option for them to leave the pets with, I am the best aunty for them and I spoil them with love but I respect the owner's rules.

I am always on time to give them food and treats, I clean the litter box and I give them cuddles and love, I check if the water is fresh, if not I change it. If the owner wants me to, I take the mail and wipe the dust and water the plants in the house. If the pet is on a special diet, I make sure it gets the correct food and the correct quantity. If it is necessary I can brush the cat. If the cat is not friendly with strangers I will not stress it with affection or cuddles.
