1) Critical times - power to kill must be curtailed (9)
R???L?N?S (The only result from a solver search seems to be RATTLINGS, but I can't make it fit)
2) Material put forward for wild animal to eat (8)
???O?I?E - Wild animal is presumably an anagram of lion giving ???OLINE, with put forward giving the first three letters
3) Models no longer rather bulky - small! (8)
E?????E? (third letter is third letter from clue one, fifth letter is second letter from clue two)
Any help much appreciated.
