One of my favourite pets of all time. He looks amazing with his frosty whiskers, breath and aura but is a great battle pet too.He even has his own NPC and backstory, how cool!

I like his versatility with having Beast and Elemental moves. Pounce is awesome as he almost always hits first with a 325 speed rating, this combats his lack of power which I have found the only downside.

Also you cant be a true Crazy Cat Man/Lady without him in your collection :P

Well worth the achievement grind!

Sagcat has it right - Biggles' current rating doesn't even make him top 20! That's crazy!


He has Pounce to take out Critters that would normally be most dangerous to his Undead type (and he's a natural S/S to get that extra damage). He has Ice Barrier for survivability or swaps. He has Ice Tomb for a stun every 5 rounds. And you can pop the Tomb while Barrier is up without blocking your own attack! OR, he has Frost Nova/Howling Blast for pure DPS!



Bigglesworth deserves better, people!

When you can solo a Celestial, you get 5 stars.

3.87 (current battle rating) seems unduly harsh.

I can't believe noone else mentioned this but Mr. Bigglesworth is not your average undead kitty.

He's a frost specced kitty death knight.


That alone makes him the greatest cat pet in the game, even though my faithful Feline Familiar is still better at soloing draenor pets for taming/leveling.

Worth obtaining not just for the collection achievement, but as Marclargoner said, he takes out Yu'la brilliantly - and thank you, first person to work out that strategy.  There's nothing like a fight that takes so little effort in trade for concentration.



He also counts for Crazy Cat Lady/Man.

Fastest undead pet available, barring speed buffs. Will actually destroy critters with the slot 1 ability, something most undeads would fear. Nice combination with Forst Nova and Howling Blast for a slight AoE. But Ice Tomb is probably a better ability to use, except if you face pets with evade moves. Ice Barrier has alot of uses, but you have to be careful that you don't block your own attacks(especially Ice Tomb). Solid pet with lots of uses.

Mr. Bigglesworth is VERY useful for the Celestial Tournament as he can solo the last fight with Yu'la with no problems :) Follow the rotation : 

Claw > Ice Tomb > Ice Barrier > Pass > Claw > Claw and then repeat :) I've used this 7 times now and it hasn't failed once :)  He's also very useful in PvP, i find him a great counter against the Mechanical Pandaren Dragonling which is becoming very popular in PvP.

Mr. Bigglesworth is a wonderful pet, not least because you rescue him from the 'reception area' of Naxxramas where mean players like to kill him just for laughs.  Poor little cat.  Rescue aspect aside, he is fun to get because it's a fight to earn him running once-weekly old content raids to get bosses to drop pets for the Raiding With Leashes achievement.  It took three weeks to get him, with help from my husband tanking.  It's fun to run old content too, nice memories!

I really like to have Mr. Bigglesworth in my collection! I'm working on it and I hope that I can help him escape out of Naxxramas, soon. ;)



Did you ever have the addon Comix? Then you maybe remember this:


"That makes me angry. And when Dr. Evil gets angry, Mr. Bigglesworth gets upset. And when Mr. Bigglesworth gets upset… people DIE!"  ^^

My friend and I had different 'holes' in our Raiding with Leashes achievement. We each crated the pets the other was missing, swapped them, learned them, got the achievement, re-crated the borrowed pets, swapped them back, re-learned our original pets.


Achievement earned and zombie kitty obtained, without having to rush for drops or spend hundreds (or thousands) of gold!

Just got mine today, but imagine my surprise to find not one but THREE in my pet journal.  I was worried when he didn't show up right away, but apparently he was bringing friends :)

I finally took the time to level this pet to 25, and he's a BEAST. His moves are pretty awesome, I use him a lot on my main team because his levels 20, and 15 moves both stun and have a nice amount of dmg. When fighting with him once he gets down too low on health I save the orb for when he comes back to life that way he helps the next pet that fights. Only real con to him is his health cap, I wish he way a bit stronger in that department, but with his moves I guess I can deal with it.

Finally got this little guy today, he is awesome.  I have noticed though that every time I log onto another toon he duplicates in my pet log, I now have several of him.

Sad about his stats though: as undead speed is not really needed, one will get the attack anyway.

This cat is not just a siamese. First off, he's undead. Secondly, he is summoned in big blue ball of frost. His whiskers are like icicles and he seems to exuberate frost from him.


I for some reason have three copies of him? Don't know why but I can't put them in cages. Also, if he does not appear in your journal after completing the achieve, just re-log.

I am sooooo in love with him!  Looking at the screenshot/pet icon...he is just another cat., person, he is soooo much more!  He has sparkles on his whiskers and Path of Frost effect, plus glowing blue eyes! 


Thank you Loki and Talerin for helping me complete the achievement for this adorable guy!

Upon exiting the freezing necropolis of Naxxramas, Mr. Bigglesworth promptly found a warm spot in the sun to take a long nap in.
