Today my old rescue dog lost control of her bladder and my rescue cat threw up on the rug. It was nice to see this on FR. It reminds me of my duties to these pets.
If it continues to happen, a trip to the vet may be in order. Older spayed females can develop this condition and it is controllable with medication.
One of our min-pins did this so we took her to the vet.
As it turns out this is a early indicator of diabetes. She is on medication and doing fine.
