I live in CT and it has been hot and humid. 94 degrees today! Merlin must be enjoying his freedom again. The ears continue to be a mystery you say. Hopefully your vet will have some sort of answer to what it is? Oh my a vacation for me is a bit difficult with the amount of little pets I have. I’m a person who enjoys being home when I’m not working.I’m out in the country and I was able to put up an outdoor enclosure for my cats which they love. Spring, summer and fall that is. My yorkie had lesions that were visible and hair loss began around the lesion. I have cultured all the pets and will do so again next weekend. I am wishing you the best with your travel plans and having a pet sitter come in. I’m sure your Mom would be very happy to see you. Hiking in Scotland sounds amazing. I enjoy kayaking here in Ct. It is beautiful and relaxing to be on the water.
