Short Songs

What's the general consensus on the animal thing? Should the songs be about animals (or pets) rather than just feature a reference in the title?

The Super Furry Animals track 'Fuzzy Birds' and Lambchop's 'My Blue Wave' are both heart-felt tracks about pets. The former is an ode to a lost dog, while the latter is a dialogue between SFA guitarist Bunf and his pet hamster Stavros:

[Bunf:]
Hamster, turnin' round in your wheel
I've got something to tell you:
I can harness your feel
Dynamo for electricity
You empower my feelings
Give me light for me to see

[Stavros:]
So won't you give me some food?
I really need to get some energy in me
Give me some
I really need to get some energy in me
Give me some
The world is turning, kicking, screaming 'round my little head
To spread it on my bread
Don't you know that I spread it on my bread?

[Bunf:]
Rest yourself you've been long on your feet
If I buy you a matchbox
Will you keep it all neat?
Radiate, you're no flash in the pan
You're the battery incarnate
I'm an innocent man

[Stavros:]
So won't you give me some food?
I really need to get some energy in me
Give me some
I really need to get some energy in me
Give me some
The world is turning, kicking, screaming 'round my little head
To spread it on my bread
Don't you know that I spread it on my bread?

Is this the kind of love we should all be spreading through song? Please tell me off for being such a softy.
