I am stupid and forgot to write down the code, but I got two with something to do with a warm up catalyst something or other. This is probably not enough information and my dad cleared the code, but any help would be appreciated

 

Most likely an inefficiency of the cat (which is the cat or the secondary O2 sensor), or too long a warmup time (any of the O2 sensors). Scan again and post the codes.

 

The code is cleared and there is no CEL now, I will re scan if it comes back I suppose. But is this anything to worry about? Effect the performance of the car?
