We have two cats who I rescued from CP back in 2006, approximately 15 & 16 years old now. The younger one has recently been diagnosed the hyperthyroidism & howls constantly during the night. I took her to the vets and they prescribed thyronorm to begin with which did improve things slightly but then she started suffering with puritus which made things worse again. She’s a very nervous, sweet cat but would not tolerate other treatments & I really don’t know what to do. She wakes us all every night & her quality of life isn’t fantastic I’m sure, she’s always so nervous & is a very fussy eater. We have discussed PTS as an option but I really don’t know what to do for the best. Has anyone experienced anything similar please?
