Sadly, we lost one of our cats at the start of last week. She was 11 and was found in a neighbour’s garden. There were no injuries, so looks like natural causes. 
Then our old boy (16) started to go downhill. Wasn’t eating, lost lots of weight, scruffy coat. With hindsight though, he’s not been 100% for a while. He was so weak we thought we were going to lose him.
Vet gave him steroids and antibiotics, but still no improvements, so they kept him in overnight on a drip and ran tests. They’ve discovered he’s diabetic. He has ketones in his urine and started insulin on Thursday and is now home with us.
I’ve joined the FDMB fb group as recommended on here, but I’m finding it a bit overwhelming.
We really thought we were going to lose him, so it feels like we’ve been given a second chance. Any advice gratefully appreciated!
