I grew up with a cat, who, as she got older, had to be medicated and cleaned. I looked after, by feeding and medicating, an elderly cat for a neighbour for a period of 2 weeks 3 or 4 times, I now have a dog (large) and therefore have experience feeding, walking and cleaning up after. We adopted her so we had to train her, and therefore I know how to walk a fearsome dog who tends to bark at people and other dogs. I've also had odd jobs growing up feeding cats, and looking after dogs (young and adult) with feeding, walking, and cleaning up after.
