Part 2

DM 14312 22a It's found in trap possibly with tail missing (3) RAT. Why?

4d Bird with this sulky behaviour may be unpredictable (9) PETULANCE. Why?

21d They're cross, upset about spelling practice (7) S-R-E-Y. Presumably SURGERY, but why?

DM 14318 17a Animal in rivertaking oxygen for energy (5) RHINO. Why?

Thanks all
