Few weeks ago i deployed applications that helps manage animals life, medical treatment, documentation, reminders, etc.
We are using it in out shelter with more than 200 animals and it makes our life much more easy, the same at my home with my 13 cats, it also saving much time and remove headaches.
I recommend you give it a try.
