Struggling to finish this one - some answers are "themed" (and are undefined), the answers being cats or dogs, both fictional and real. Lack of space means that I can't provide the full clues, but I'd be grateful for help on 18a and 30a, and 10d, 13d and 54d (?could be "giallo", whatever that means. Thank you, and a Merry Christmas to all (especially to those who give me a hand with the above......).
18a Rumtumtugger (yes, I know, it should be 3 words) - 'um' + anag 'mutt' (in) 'rugger'
30a Toms (not themed)
10d Rum-pus(s)cat (again, should be 2 words)
13d Hairnet - anag 'the rain'
Hi AMartinP - it's always nice to include the full clues, numbers of letters & to show any you've placed so that people without the puzzle can more readily help you :-)
