Sick pets can be annoying, but they're practically IMPOSSIBLE in rotational play

I dont see that many sick pets really, but I dont play Brindleton Bay and I am loving the pets in this ep...my one problem is that my pets get sick alot if you have one of the big bushes on the lot, the ones you can also use for wohoo, like my pets would go into them and fight something, get bitten by squirrel and get sick every two minutes, or sprayed by a skunk, I just sold the bushes and that solved
