what is your favorite pet care book(s)?

I'm interested in buying more pet care books so that I may expand my library (my b-day is coming up so I need a list of books I'd want as presents); I'm interested in books about:
cats
dog breeds (reference for choosing/distinguishing dog breed)
positive dog training
hermit crab care
hamster care
fresh water aquarium care
betta fish (chinese fighter fish)
tree frogs and care
keep in mind-all animals interest me so any book about animal breeds or animal care or animal training will interest me…
I already have alot of these books but most of them are ones I've already memorized so I'd like some new titles to read for my birthday—thanks ya'll!
