I'm very glad that Tigris is on the mend.

About the hissing thing - when we have to keep Daisy in to give her antibiotic and ointment when her infection flares up, Samantha hisses at her. I don't think it has to do with the smell, sometimes we haven't even had to take Daisy to the vet, On the whole, I think Sam is just a little madam who does not like the disruption to her household!
