<human>: Can you provide a brief overview of the text?

I lived in a mid-rise apartment in the Dallas, TX area and I'm not sure what I should do here. A few months back I took in a stray dog who was quite literally starving to death on the side of the road, and after calling a few shelters to see if they could take the dog and being either denied or ignored at each, and also not wanting to take the dog to the pound just yet, I cleaned her up and let her stay in my apartment for about a week (most of the time was spent in my abnormally large bathroom). I found the dog a home a week later and didn't think anything of this until just recently when I realized that part of the bathroom door was damaged at the bottom. Just some really deep scratches is all, but none the less damaged. I sanded down the scratches and planned on just painting over them myself, but the property manager told me not to when I told asked what the exact color the trim was. 

I am now moving apartments and I told the the assistant complex manager that "there was some scratches to the bathroom door and part of the trim that I had sanded down due to damage" he asked me to send him some pictures of the damage that I had mentioned so that they could assess the damage (not sure why he wouldn't just come look). I sent him the pictures and he immediately responded with "Is this pet damage?" ... so here we are .... obviously it is pet damage, but I have not told them that yet ... and I never paid a pet deposit or pet rent or anything because I didn't have a pet. I know I broke their rules and honestly I feel bad about it, but I feel like they're going to murder me with charges over a cheap interior door that may or may not need to be replaced, and a trim piece that can easily be painted. 

I have not yet responded and just need to know whether I should explain the situation, or just not say anything and let it ride? Or say we got REAL drunk and who knows what happened next? 

Thanks for any help in the matter!
<bot>: Took in a stray for a week, it tore up the bottom of a bathroom door in an apartment that I never paid the pet deposit for or pet fee for. What's the worst that can happen?
