I think the vet underestimated just how active these two are. Add to that two very rambunctious and curious older siblings, and I'm not sure the cones stand a chance. We were going to take them in at 14 days to have the stitches removed but may end up taking them at 10 or 11 days just so that we can get new cones.
Thankfully, the littles are doing better than their cones. They have been flying around the house at top speed, chewing on Mr. C and Miss B and eating whatever they can con us into giving them. All four of them love when it's time to put the antibiotics on their ears because it means that the peanut butter jar comes out. They sit really still for us as long as we keep the peanut butter coming.
