The Church Mice Series by Graham Oakley

When Arthur invites the other mice to live in the church, it doesn't take long for people to notice the rodent population explosion! It will take some very brave mice and one fairly courageous cat to persuade the townsfolk to welcome and embrace the newest members of the congregation.

Everyone in Wortlethorpe, including the church mice and Sampson, the church cat, hoped the holiday curate would be a nice quiet chap like the one they had last year.He wasn't.What's more, this trendy young curate hated mice, and considered it a church cat's duty to catch them, not to hob nob with them. Changes, changes . . . but the worst change of all was NO CHEESE.Plainly, something had to be done.

When Arthur and Humphrey decide to rally the church mice into having a Christmas party, the result is a series of disasters.
