I believe every animal has angels looking after it and when they cross over they are guided back 'home'. But you may notice that 'home' sometimes is still right around us. We can often feel their presence in the days that follow. I've felt my (passed) kitties walk on my bed and have even seen them out of the corner of my eye scurrying across the room. I think they hang around for a bit until they decide we are doing ok and then they can move on to other things. Animals, with their pure spirits- give us unconditional love. It's no wonder why we find it so hard to let them go.
