I am so sorry you lost four cats in such a short time! My goodness, that would be more than I could take. Were they all about the same age? :o(
Sorry it took so long to get back to the thread and see your posts. Haven't had a lot of FR time lately.
The four kitties we lost in so short a time were older cats......13 to 16 years old. Two had cancer and two had kidney failure.
It was heart-wrenching to let them go but at least I knew they'd had long lives filled with being spoiled rotten.
We still have three who are 13 yrs. or older so I know I'm not through yet. After them, the next oldest are almost 9 yrs. old so we should get a little break. :-)
