Hi, no worries about not knowing all the technical terms, even the best in the business sometimes struggle with that there are too many words to keep track of. From what you have shared it looks like there are going to be two directions we can take in approaching the solution. If you want to just get data and no update it all you will need is a simple web scraper which is a pretty easy thing to get working. If you want the data on your app to update as data on pet store web pages are updated you will need a little more than that and it becomes a little bit more of a complex process but either way totally doable. I have lots of experience in working on web apps that serve (give to users) both static (non-changing) and dynamic (changing) content so I will be well prepared to help you with your solution regardless of the direction you would like to take.
