Answer:
15 branches
Explanation:
First it went up to the sixth branch.
+6 = 6
A big squirrel scared the kitten, and it claimed down three branches
+6 -3 = 3
a bird flew at the kitten and scared it again . Now it claimed up 10 branches.
+6 -3 + 10 = 13
The kitten claimed back down 2 branches
+6 -3 + 10 -2 =11
and then went up 4 branches to the very top of the tree.
+6 -3 + 10 -2 +4 = 15
