I got a weird problem involving both of my cats (Siegfrieda, to the left; Kika, to the right).
Kika is rather particular about having her own litterbox(es), and refuses to use a litterbox shared by another cat. Frieda on the other hand is adept to the “if I fits, I sits, I shits” philosophy, and is totally OK sharing litterboxes.
That creates a problem: no matter if properly and regularly cleaned, the only one using litterboxes here is Frieda. We had, like, five of them at once; and Kika would still rather do her business on the patio.
How do I either teach Kika “it’s fine to share a litterbox”, or teach Siegfrieda “that’s Kika’s litterbox, leave it alone”?
I know there are feeders that use a collar tag to only allow food to specific cats. Maybe there’s a litter box with a door that has the same tech?
I’ll give it a check. If this exists (and if it’s available in Brazil, and reasonably priced) it would solve my problems really well. Thanks for the idea!
I can confirm they make pet doors with this technology. If you can’t specifically find a litterbox that has it, you could build a DIY box that does.
