Hi Laura, thank you so much for replying.

We actually brought her to the vet a few months ago because of a fight bite she got from one of her outside trips. While the wound was not anything to worry too much about, we talked to the vet about letting her outside and expressed our worry (she’s gotten scratches before but it was the first time she got a bleeding bite wound), and the vet agreed that she should stay inside from then on.

Aside from the wound she was overall fine, thus why I believe these are stress symptoms…

As for the catio option, we are renting, and while we do have a garden, we share it with the landlord, so I don’t think it’s a viable option right now.
