What do pet owners do?

The person who takes care of those pets in the pet farm.

Catering, feeding, cleaning, observation, basic treatment and so on. It's all the work of breeders, who usually live in breeding grounds for a long time.

Not only cats and dogs, but also fish, mice, snakes, turtles, spiders, lizards and so on are possible, depending on what the recruiter does.

I'm not asking you to see a pet. I mean, for example, if the vet sees it and gives it to me, tell me how to take it, and then the medicine feeding work will be yours in the future.

Whether you can apply depends on your communication with the recruiter. In some places, you don't need any relevant experience and knowledge, as long as you are willing to work hard. Other people need feeding experience or knowledge. Anyway, if you want to do it, just talk to others and ask.
