Thanks for all of your kind and helpful comments. Mum did take me to the vet only a week or two ago and is pretty happy that health wise I am ok. Going to the vet is a bit traumatic so she will wait for my next appointment to get my bloods checked. Besides the calling out to her I am pretty happy, eating drinking as normal.
I've got mum home for 3 days now and mum is looking forward to some sleep ins and naps with me.
