nice use of collect which is an alias for .map.

you could also write this input.map(&:capitalize) or input.map {|s| s.capitalize}.

be sure to take a look at the Symbol#to_proc method. it's very common.
https://ruby-doc.org/core-1.9.3/Symbol.html#method-i-to_proc

word.capitalize
end
end

nice. in most cases, we'd write this input.reject { |animal| animal == "dog" }. same with .select above.

animal == "dog"
end
end

#implement your solution here
input.count

cool. you can also use .grep which takes a regex pattern. it's super handy.
https://ruby-doc.org/core-2.5.0/Enumerable.html#method-i-grep

animal[0] == "c" || animal[0] == "d"
end
end
