BogBastardKitten has had a hooded litter tray since arriving home in August aged 3 months. After repeat performances of him appearing with a crap-covered bottom I wondered if his now enormous size (Siberian, not quite as big as a Maine Coon but getting there) meant he was being squashed down into his own doings. Therefore removed the lid from the tray to make it open. Tray now not used since yesterday morning. BBK full of beans and not obviously unwell or distressed.
A) is this a strike due to unfamiliarity? B) if A, which of us is likely to crack first and c) when should I worry about non use of litter tray and seek vets advice? If cat otherwise well and eating, drinking etc?
