Oh, wow- I've noticed you logged in here, just thought (hoped?) you didn't feel like posting. Sorry to hear you've been in the hospital again, that's the pits. And you don't have to convince me- no one would blame you one bit if you decided to further reduce your collection- all those animals cause you stress when you can't keep up, & some aren't ideal for Katie either.
There's no one right number of pets to keep that fits everyone- we're all walking a different path, & over time, that path will change too. One person might be fine with 40+, another might be overwhelmed with 3- so listen to your own inner voice on this- & maybe talk it over with Katie or others too.
Glad to hear you're on the mend again, & hope the changes help you a lot.
