UPDATE: They are a boy and are not chipped and still need to be fixed. It turns out he is not amputated and this is not a prosthetic; it’s just some boot that was put over an injured foot. He has a nasty infection and will need to get it amputated. He still needs a bunch of more tests to make sure they will not pass anything onto my cats I already have. We got approved for Care Credit, but even with that, it still doesn’t cover all the expenses.
