The Cats and Dogs pack was quite a large expansion and proved to be an issue for quite a lot of people, I'll give you 2 links that may help you with the requirements for the game to run well.
If you use Mods & cc they are well known to cause various in-game issues please check for updates to them / where you found them; do this also
Apart from culling your folders one by one, or the 50/50 method, to narrow down the broken cc or mod, that is all you can do, (restarting and checking your game each time) you'll simply need to find the broken mod/cc it and remove it.
Let me know if you still have problems.
Hope this helps, Sasha

Hi @Hel1ne28 are you still experiencing the problem?
nb: Checking the requirements of the Cats and Dogs pack as previously explained or removing your mods and cc if you have them?
