That's an enormous improvement to her heart from 6mm to 4mm. It puts her
into the range of normal again so well done for picking it up so quickly.
I`ve had several cats, including non-HCM cats open mouth breathe when heavily
stressed like at the vet. This includes Lexi who was HCM scanned negative
and has no heart issues. So it may be a stress event.
When is her next scan due? I`ve never had a cat who has gone back to a
normal wall thickness, What else did the scan report say about the heart? I`m
not sure about the medications, if she was progressing, I`d say up the
cardio Strength to one a day, but she isn;t. She's clearly improved.
