Ration food and eat things that are perishable first.
Prepare the safest room in your dwelling as a bunker. Hang heavy blankets around windows and doors.
Pack vital items into a go-bag and make sure you know where it is at all times. Passports, ID, cash, gold jewelry/valuables, small sentimental items, medications, phone charger, laptop.
Electricity may go out- charge all your devices and any backup batteries you may have. Use them as little as possible for now.
Keep some flashlights and batteries in a bag or box easily accessible.
Know which of your neighbors you can trust and what skills they may have so you can help eachother.
You can often trade liquor and cigarettes for other valuable things you may need - if you have any, reserve them in case you need them.
If there is something valuable that you cannot take with you but must protect, bury it.
Keep your head down, do not draw attention to yourself. If you must do anything that may look suspicious, act like normal & move with confidence. Most people will not question someone who is purposefully doing a task and not acting suspicious.
Get to Slovakia, Poland, or Romania. Their borders are open to refugees. Bring your passport. I don't know what sheltering as a refugee will be like with pets. A kind citizen may be able to take care of them for you temporarily if you get them across a border. Just do your best. You can only care for them & your loved ones if you care for yourself first. Difficult decisions are made in times like these. ***edited to add, contacts in each of these countries have confirmed they are currently accepting refugees, no Visa required, but passport is required. Keep your passport on your person at all times, close to your body, wear a small fanny pack or belt bag under your clothes or duct tape it on your torso inside a zip lock bag or wrapped in a small cloth if you must. Desperate people may try to take one if they don't have one or can't find theirs. (2)
