the longest I've been away from Buffy was 3 days, and Willow 2 weeks. When Buffy was 4 1/2 months old and Willow 2 1/2 years old, the whole family went to BC (British Columbia) for a funeral for 3 days, and when we returned, Buffy came racing from my sister's bedroom, spinning and slipping all over the floor, desperate to come see us. I was so hopeful that she was coming to me, that she remembered her momma, but she ran right past me to my mom
. Willow just calmly walked out of my sister's room (they had been in there because they were watching our car arrive through the bedroom window) and had a "So, what'd you get me?" look on her face. We had put out something like 5 bowls of food and water (more than enough for 3 days) and when we came back, all were empty. I have suspicions that both cats ate it all within a day or two in misery ("Where are the humans? Are they coming back? They left us, didn't they?!").
Me, mom, and my brother went to Ontario in 2002, when Willow was a year old, and we stayed for 2 weeks. When we came back, I don't think Willow cared, because my sister and dad were home with her. Plus, she's not one to show emotion unless she gains something out of it, lol
As for Jake (my dog), its the same kind of hysterical "you're home!!!!" dance every time, whether we're gone for 10 minutes or 2 weeks
