cat goes "Meow"

We are all familiar with the concept of a cat program. The user types something in, it is echoed back to the user. Easy. But all cat programs I've seen so far have missed one fact: a cat goes "Meow". So your task is to write a program that copies all STDIN to STDOUT UNLESS the input is cat, in which case your program should output cat goes "Meow".

Scoring

This is , so your score is your byte count, with a few modifiers:

  • If your program works for any additional animals other than cat (e.g. cow: cow goes "Moo"), for each additional animal: -10
  • If your program doesn't use the word "cat": -15
  • If your program responds to fox with "What does the fox say": -25

Animals and sounds that go together:

cow goes moo duck goes quack sheep goes baa bees go buzz frogs go croak

Anything else on this list is allowed.

Rules

  • Standard loopholes apply
  • You must not write anything to STDERR
  • You can use single quotes/no quotes instead of double quotes.

Leaderboard

Here is a Stack Snippet to generate both a regular leaderboard and an overview of winners by language.

To make sure that your answer shows up, please start your answer with a headline, using the following Markdown template:

## Language Name, N bytes

where N is the size of your submission. If you improve your score, you can keep old scores in the headline, by striking them through. For instance:

## Ruby, <s>104</s> <s>101</s> 96 bytes

If there you want to include multiple numbers in your header (e.g. because your score is the sum of two files or you want to list interpreter flag penalties separately), make sure that the actual score is the last number in the header:

## Perl, 43 + 2 (-p flag) = 45 bytes

You can also make the language name a link which will then show up in the leaderboard snippet:

## [><>](http://esolangs.org/wiki/Fish), 121 bytes

The program is 27 bytes bytes long and doesn't use the word cat (-15 bytes).

Try it inline in the CJam interpreter.

How it works

q_                e# Read all input and push a copy.
:)                e# Increment all code points of the copy.
"dbu"=            e# Push 1/0 if the result is/isn't "dbu".
" goes \"Meow\""* e# Repeat the string that many times.

JavaScript, 45 - 15 = 30 / 264 - 235 = 29

Downside: you have to write the name of the animal with the first letter in uppercase and the rest in lowercase. Look below for another version which fixes this. This version escapes the a in cat with \x61 and includes code for the 22 extra animals from this list (all the allowed animals which had short enough words to be worth it):

bee buzz 7
bird song 8
cattle moo 9
cow moo 6
crow caw 7
dog bark 7
duck quack 9
frog croak 9
horse hiss 9
hog oink 7
lamb baa 7
lark sing 8
lion roar 8
ox low 5
pigeon coo 9
rook caw 7
seal bark 8
sheep baa 8
snake hiss 9
swan cry 7
tiger roar 9
whale sing 9

(thanks to my friend for helping me with the tedious task of making this list)

Ungolfed code:

data = 'MeowBuzzSongMooMooCawBarkQuackCroakHissOinkBaaSingRoarLowCooCawBarkBaaHissCryRoarSingC\x61tBeeBirdCattleCowCrowDogDuckFrogHorseHogLambLarkLionOxPigeonRookSealSheepSnakeSwanTigerWhale'.split(/(?=[A-Z])/);

input = prompt();
index = data.indexOf(input);
sound = data[index-23];
result = sound ? input + ' goes "' + sound + '"' : input;
alert(result);

First version, 45 bytes - 15 bonus = 30

alert((i=prompt())=='\x63at'?i+' goes "Meow"':i)

Yes, I know. I went from 30 to 29 with ALL that extra work. It was fun!

Version that allows full lowercase input, 294 bytes - 235 bonus = 59

alert((s=(d='MeowBuzzSongMooMooCawBarkQuackCroakHissOinkBaaSingRoarLowCooCawBarkBaaHissCryRoarSingC\x61tBeeBirdCattleCowCrowDogDuckFrogHorseHogLambLarkLionOxPigeonRookSealSheepSnakeSwanTigerWhale'.split(/(?=[A-Z])/))[d.indexOf((i=prompt())[0].toUpperCase()+i.slice(1))-23])?i+' goes "'+s+'"':i)

I also tried removing casing from the data array with .join().toLowerCase().split(',') but it ended up taking 297 characters instead.

Java = 222 bytes (compressed)

public class A {public static void main(String[] args) {Scanner a=new Scanner(System.in);for(;;){String b=a.nextLine();if(!b.equalsIgnoreCase("cat"))System.out.println(b);else {System.out.println("meow");System.exit(0);}}}

Or I could decompress it.

Batch = 52 bytes

set /p k=

Javascript: 48 Characters, 48 Bytes

function(s){return (s=="cat")?"cat goes meow":s}

Test

=>"Dog"

<="Dog"

=>"cat"

<="cat goes meow"

  • \$\begingroup\$ Good work! You could drop the parentheses around s=="cat". Also, the cat's string is supposed to be cat goes "Meow", so 'function(s){return s=="cat"?'cat goes "Meow"':s} is completely valid. \$\endgroup\$ Nov 8 '15 at 20:53
  • \$\begingroup\$ If you wanted to save even more, you could use ES6: s=>s=="cat"?s+' goes "Meow"':s (30 bytes) \$\endgroup\$ Nov 8 '15 at 20:54

Haskell, 52-15 = 37 bytes

c"\99at"="\99at goes \"Meow\""

Using \99 as a substitute for c in “cat” so as to get the 15 bytes bonus.

I finally got around to converting my new functional Python 2 entry to Pyth. It doesn't beat the top contender. Turns out zipping together more animals into a larger dictionary reduces score faster than cleverly associating animals with sounds. This supports 8 animals in addition to cat: rhino, okapi, moose, lion, tiger, badger, hippo, and stag.

Japt, 25-15=10 24-15 = 9 bytes

First time trying Japt:

N¦`¯t`?N:`¯t goƒ \"´ow\"

ƒ should be replaced with unprintable character U+0083 Compiles to:

N!="cat"?N:"cat goes \"meow\""

Old solution:

N¥`¯t`?`¯t goƒ \"´ow\"`:N

C++11, 316 - 11*10 - 15 = 191 bytes

#include <map>
#define t(a,b){#a,#b},
using s=std::string;int main(){std::map<s,s>m{t(cow,moo)t(crow,caw)t(dog,bark)t(hog,oink)t(lark,sing)t(lion,roar)t(oxen,low)t(rook,caw)t(seal,bark)t(sheep,baa)t(swan,cry){"c""at","meow"}};s l;while(int i=~getchar())l+=~i;printf("%s",(m[l]==""?l:l+" goes \""+m[l]+'"').c_str());}

Compiles well with VisualStudio. GCC wants me to #include <string> and #include <cstdio>. It would be shorter if I wouldn't go for bonuses, but I still hope author revises bonuses. I can't think of language where defining cow -> moo or so is way way shorter than 10bytes. Mine cost 3+key+value bytes for additional animal and flat 22+17 bytes for defining structure and so.

Ungolfed

#include <map>

#define t(a, b) { #a, #b },
using s = std::string;
int main()
{
    std::map<s, s> m{
        t(cow,moo)
        t(crow,caw)
        t(dog,bark)
        t(hog,oink)
        t(lark,sing)
        t(lion,roar)
        t(oxen,low)
        t(rook,caw)
        t(seal,bark)
        t(sheep,baa)
        t(swan,cry)

  • \$\begingroup\$ "t(crow,caw)" has a length of 11. So getting rid of that to "t(swan,cry)" would drop 14 bytes. And admittedly make it less fun :( \$\endgroup\$

Try it online!

Example

."c""at"+=" goes 'Meow'"*   # Input: cat
."c""at"                    # Duplicate input, push c and at. Stack: cat cat c at
        +                   # Concatenate, Stack: cat cat cat
         =                  # Check if equal, Stack: cat 1
          " goes 'Meow'"*   # " goes 'Meow'" pushed onto stack n times, Stack: "cat" " goes 'Meow'"
                            # Implicitly print

Alternate Example

."c""at"+=" goes 'Meow'"*   # Input: asdf
."c""at"                    # Duplicate input, push c and at. Stack: asdf asdf c at
        +                   # Concatenate, Stack: asdf asdf cat
         =                  # Check if equal, Stack: asdf 0
          " goes 'Meow'"*   # " goes 'Meow'" pushed onto stack n times, Stack: "asdf" ""
