Always others

The older cat has moved to the kidney disease infusion stage. The younger cat continues racing through the house. This is the way of things. 

There must always be
Two cats
One older
One younger.
There is learning here.
Not just for them
Also for us.
When one sickens
Then dies
Another must be found.
This is the way
Of living creatures
Even cats
Who might prefer
To reign over
The household
No 
We say
There are always
Others
Don't forget
There are always others
Even if
One is
A cat.
