Who Dunnit?

I present to you the classic 'who dunnit' scenario. Two suspects and only one guilty party. Judging purely from the photographs, it is very difficult to say which of the two suspected characters could be responsible for the damage done. Here I have Exhibit A:


Clearly you can see that damage has been done. I, being the detective in this situation, decided to clean up the mess so as not to give the suspect reason to return and finish the damage. As you can clearly see, the toilet paper has been unraveled and shredded beyond use and recognition. In a house of two kids and five cats, the possibilities are endless. The first to return to the scene is seen in Exhibit B:

Due to lack of declawing, it is apparent that suspect "Penny" was possibly returning to the scene to further the damage to the poor unsuspecting roll of toilet paper. But upon investigating, a second suspect returned to the scene of the crime. See Exhibit C:

Due to the age and pure nature of the above suspect, it was even more clear to me that there was indeed a very good chance that suspect "Abby" was also fully capable of rendering a perfectly good roll of toilet paper unusable. After interrogating the suspects, the crime was solved. Let us see who was responsible for the toilet paper's ultimate demise...

Case solved.
