Animal Care Needed

We are moving and will be staying with family for a minimum of 6 months and they are severely allergic to cats. We dont want to separate from our cats they are our family but we wont be able to have them with us while moving. All cats are well behaved, loved to snuggle, play with each other a lot, have their own automatic cat feeders, water fountain, an automatic litter box, a standard litter box, and a large cat tree
