So Many Accidents...
I have a 19 year old female cat Marilyn, who, because of her bad legs, finds it difficult getting out of the catflap now, so we put a litter tray inside for her.
She sometimes seems to have difficulty peeing (she still poos outside) because she'll squat over the tray and nothing will happen. Then she search all around the house meowing loudly and trying to pee in the wrong places, but still nothing coming out. We let her out the front, and she'll stay outside for a bit, then come back in and do the whole thing again, though she sometimes pees on the carpet once she comes back in.
Last night she was peeing all over the house, in every place except the litter tray. She couldn't seem to do anything in there, but she could on the carpet. My dad was getting very angry with her, and I got sad beacause she really can't help it; she's so old.
Marilyn also has hyperthyroidism and is deaf as a post. Is there anything I can do to help her?
