Do you find that your cat catches horrible bugs and brings them in the house too?

i am thinking of removing the cat of my van as its showing cat performance low and bringing on the engine service soon light on after 20 ish miles even after resetting with a scanner. are there any problems with removing it and does it effect the sensors if its taken off .. steve

Was on tv last night so i had to find it, it tickled the inner child in me :):) or perhaps im just childish but i thought it was bloody funny :D
