My cat is about 6 mos. She has a food allergy. She is allergic to store brand cat food. I feed her the lamb food. She eats it but would much rather have the store bought cat food I feed my older cat. What happens when she gets store cat food her face and paws swell up. She will spend every minute of the day trying to find food to eat. She climbs on top of my stove, cabinets, counters, tables, she’ll even put her paw down the garbage disposal. She’ll tip over the garbage can. I tried the water bottle. I tried crating her when she is bad. I tried scruffing her. Nothing has worked! Please help.
I thought about putting both cats on the same diet. It would be expensive but probably save me some grief. I feed the cats separately now. I’ll see if my older cat will eat the lamb. Thanks.

You can put double sided tape down on your counters and stove or get those runner mats with the little prongs sticking up to keep her off. As for the trash can, you’ll just have to put that in a closet or cabinet or get a heavier stainless steel one with a lid. You’ll probably have to feed your older cat in another room or remove this cat while the older one eats. Scruffing, yelling, spraying water only causes a stressful environment for your cat and will do more harm than good. Try hiding treats around the house for her to hunt. It will keep her busy looking for appropriate snacks.
