Lab notes: Have recently noticed disturbing trend towards deafness in humans whilst in their bed. They definitely know I am there, but do not seem to hear my purrs or reasonable requests for food or access to the outdoors. Situation especially severe if the noise box in the corner of their room has not started beeping.
Hypothesis: humans needs trigger noises to become able to hear. Purring ineffectual, must test other sounds to find alternative to beeping box.
Test day 1: Urination in corner of room – extremely effective. Near instantaneous reaction to the sound and acknowledgement of my needs.
However, standard lab conditions jeopardised by washing of carpet and moving of furniture to deny access to my experimental area. Shall have to formulate alternate approach for tomorrow. Or maybe they will be more sensitised and respond to purring without additional prompts.
