How long have you been in this house? Have you tried setting up a place to sleep and hang out downstairs to see if he eventually becomes growly even on the first floor? All electrolytes, including IONIZED CALCIUM are within normal range?

If I am not posting correctly, my apologies: your thoughts/prayers/words of comfort mean so much to me and my family (this is going to be a “first” for my Husband and I, and our 15, 12, and 4-yo). I will keep you all posted; and thank you for all of your comments/suggestions.

Ours are confined to the porch when we leave for work. They have an adequate amount of room to move around and they also have a doggie door they can go out to access the yard. It is great, if it is nice out they go and lounge on the deck and chase those pesky squirrels and if the weather is not good they can retreat back to the porch and lay on their bed inside. They are separated from the rest of the house with a baby gate that mounts to the wall. So far, fingers crossed, they haven't been able to figure out they can jump over the baby gate and it's been 3 years since we have moved into the house.
