Matching sleep cycles?

[Trifina Resident]

I have two KittyCats, and one is sleeping while the other is awake. For some, this might seem an ideal situation, but I think it's cute to see them sleeping together and playing together out in the yard. So....

Is there away to delay one cat's sleep cycle so they match up? A perfect match isn't needed, but just closer would be nice.


Thanks in advance, and Happy New Year, everyone!
