I'll mention my top 5 favorite types of animals - all of my favorite Pokemon are in fact based on their real life animals.
1st: Overall Mustelids are my favorite types of animals! It's no wonder why I choose the name "Playful Weasel" when I had the chance to get my username changed.
• Weasels are my favorite among the mustelids family so - Mienfoo and Mienshao fit in pefectly - also Linoone fits in too.
• Otters are my second favorites among the Mustelids family so naturally Oshawott, Dewott, Samurott, Buizel, and Floatzel fit perfectly for me
• Ferrets are third among the mustelids so Furret can't be missing.
2nd: Not sure what Latin name they gave the Mongoose/Meerkat family, they are also tied in first with Mustelids as my favorite types of animals is Watchog (its my #1 favorite)
3rd: After Mustelids and Meerkats - Felines are next as my favorites (cougars are my favorite non domestic cats - and the Abyssian is my favorite domestic breed)
so to name a few - Meowth, Persian, Skitty, Delcatty, Shinx, Luxio, Luxray, Glameow, Purugly, Purrloin, Liepard, Litleo, Pyroar, Espurr, and Meowstic
4th: Recently I been liking foxes, thanks mainly to Braixen!, so I could consider them fourth in my favorites - such as Eevee (most Eeveelutions are based on partial foxes), Vulpix, Ninetales, Fennekin, Braixen, Delphox
5th: Not sure what their family is called, but after the ones I mentioned above, raccoons are next in my favorites - Zigzagoon is the main one that comes to mind there should have been more raccoon based Pokemon.
by the way it was interesting and I enjoyed reading the other responses.

instead of 'Catch 'em All' for me would be "gotta Pet 'Em All"
