To add to what chort said, it's also possible to do it with Oclhashcat-plus if you use dictionary + rules. You have bugs as a dictionary, use a first rule file to add the 00, 01, 02, etc, a second rule file containing the "rulified" animals.txt like $d$o$g, $c$a$t, $c$h$i$c$k$e$n. Finally, a third rule file that adds the symbols $@, $%.
