I think you must consider your financial position and also the effect on your cats, cos they must come first.
My recommendation is that you just dont look at these kinda adverts, sorry.
I agree with you, it is not burying your head in the sand but just common sense. Sadly we cannot save the world (but we do try)
Then again it reminded me of the poem. 'It Matters'.
As I walked along the seashore
This young boy greeted me.
He was tossing stranded starfish
Back to the deep blue sea.
I said "Tell me why you bother,
Why you waste your time this way.
There's a million stranded starfish
Does it matter, anyway?"
And he said, "It matters to this one.
It deserves a chance to grow.
It matters to this one.
I can't save them all I know.
But it matters to this one,
I'll return it to the sea.
It matters to this one,
And it matters to me."
I walked into the shelter,
Ginny greeted me.
She was helping Hope learn to trust.
She was struggling I could see.
I said, "Tell me why you bother,
Why you waste your time this way.
Hope's only one of thousands,
Does it matter anyway?"
And she said, "It matters to this one.
She deserves a chance to grow.
It matters to this one.
I can't save them all I know.
But it matters to this one,
I'll help her be what she can be.
It matters to this one,
And it matters to me."
