All creatures great and small.
Like a lot of people, we feed the birds; we've planted bushes just to draw the butterflies. We also try to keep the squirrels off the bird table, mainly due to Barney going absolutely bonkers when he sees one. And I put out cookies in a cage for the little wood mice. We put their treats in there because they are able to get in and out. I even go out of my way to catch any and all insects that get in the house and put them outside - learned that from Krip.
However, there is one creature or creatures that I don't like in my garden. Rats. We now have a family coming into our garden at dusk; two youngsters and two adults.
Having a fish and chips shop, as well as a curry house nearby doesn't help.
Rats! Ugh.
