You can use evolved forms of said pokemon (for example, if one of your animals is a rattlesnake, you can use Ekans, but can as well choose Arbok despite it not being a rattlesnake anymore).
Also, if you want to be more specific you can google "animals of -your state/province/etc-".

Here is my result:
>animals of Russia
>first six results are a Russian mole rat, a raccoon dog, a baby seal, a lynx, a Siberian tiger and a red fox
Since there is no pokemon even close to mole rat, I just chose Raticate because it has massive incisors like a mole rat and can learn Dig. And no lynx pokemon, but Purugly is a big cat with ear tufts, close enough.

Please share results and explain your choices if needed.
