Our dog’s BOB is about as extensive as ours. Fortunately he packs his own gear in saddle bags.
Small dog so I pack his food, but he carries his water bottles.
I have finally completed our woman/dog car packs since we might not be at home when shtf. This required food, water and “matching yellow” life jackets, LOL, since we must cross water to return to our supplies in order to shelter in place. Inflatable raft fits in storage compartment. No paddles yet, but the “flippers” are packed in there.
I hope I never need to use it, but am physically able and prepared!
:-)
I don’t think a cat could do that; but the pigeons might be useful for long-distance communication.
(The problem is, they were no good at their “homing” vocations; and that’s why I’ve got them.)
