Just a suggestion, feel free to ignore it.
Anyone writing to places about Price's animals:
Keep emotions out of it as much as possible, other than the obvious.
Stick to facts with evidence, dates, places etc where you can.
Avoid hearsay, he said, she said, article in the sun said etc.
Check your grammar, spelling etc (yes it matters). It doesn't have to be perfect, but it really does help if you want to sound professional.
Keep it succinct .
Don't swear.
Check what you want to achieve, both realistically and in an ideal world, and make sure you've written it clearly.
Write it, rather than email it. Or do both.
End with something along the lines of 'I look forward to your reply'.
(e.g.banning her from keeping animals - how likely is that in reality? What about those she lives with, what's to stop her saying they're their animals? How do you envisage a ban on having pets? What's the least you would find acceptable? )
Hope that's of some use.
