Of course it was absolutely not intentional 
When she had her bandage on she had to hop. She got lots of cuddles and chicken. When her stitches came out she felt a bit tender and had to hop, she got lots of cuddles and chicken.
Now she just hops everywhere
. She has been to the vets. There is no physical reason for her hopping. If you throw a treat in the air for all three pets to race to she certainly has use of all four legs. When I come in from work she has use of all four legs. When it is just me and the other pets in the house she has use of all four legs. When dd1 or DH is in the house she must hop
