Thyronorm Medication for cats (EX8)

I have recently lost my beautiful little cat. She had hyperthyroidism as well as other medical conditions. She was prescribed Thyronorm for her her hyperthyroidism. I bought a 100ml bottle shortly before she passed and have only used part of it. If there are any other cat parents out there treating this condition I would love to offer the rest of my cats medication; I know how expensive it is and I would hate it to go to waste.
