Those poor animals, sounds as though you can't handle them. Why not put them up for adoption?They shouldn't be left outside while you take a nice vacation.Two geriatric flea-infested black cats:
Nearly 14 year old male cat who will urinate and defecate on everything except the litter box. Particularly likes to poo on the seat of the dining room chairs. Lately, he makes a hornking noise when you look at him, as though he might cough up a hairball at any moment.
Twelve year old female cat has an anxiety disorder, or maybe an esophageal defect, or a combination of these two that results in random vomiting around the house. This usually occurs about 3 times per day, but up to 8. She prefers to vomit behind radiators and under furniture so that you find it months later, hardened like cement.
