If you are moving to a different state or country, most places and/or traveling services will need a certificate from your vet. This is just to say that your pets are okay to travel and that they will not bring in an illness that can hurt other species there. It's kind of like how we get a check-up if we travel outside of the country!
I am happy to say that both my bunnies got a clean bill of health and I got their certificates. This also officially means that it's finally nearing the actual move date. I'm going for my second poke on Monday so I will be good to go as well. I think after that, I will be able to breathe a little bit easier.
