AITA for calling my sibling negligent and denying responsibility?

AITA for calling my sibling negligent and denying responsibility?

So he has a dog that gets into everything if its not locked up and because of this, I made adjustments to where the trash bins are located. I bought a small drawer countertop that stores two bins inside of it, one for garbadge and the other for compost, which has successfully kept his dog out of those bins. Wasnt really my responsibility but it made the house look cleaner. But since it only had two slots, we just left the recycling out thinking his dog wouldnt get into it.

After his dog kept getting into the recycling I decided it would be best to place the bin inside the water heater closet which is already nearby the other trash bins. He didnt like the idea for whatever reason so he just brought it back out everytime i put it back in there so I eventually just gave up. As a result his dog would constantly grab cans of cat food, chili, corn, whatever i tossed in there even if I rinsed them before hand. Eventually we think he sliced his tongue on a can he took out of the recycling. I was blamed as he claims it was the cat food can and that I am an irresponsible cat owner and I should have just taken them outside into the recycling bin instead of using the inside recycling bin which I find ridiculous. I called him negligent for not keeping the recycling in the closet and told him he is to blame for this incident.
