Jack’s Weight Loss Journey

My Jack is a 9 y/o male black tuxedo. Jack has been obese for the past 4 years, and last month he weighed in at a whopping 32lbs at his vet visit. My new vet recommended

My Jack is a 9 y/o male black tuxedo. Jack has been obese for the past 4 years, and last month he weighed in at a whopping 32lbs at his vet visit. My new vet recommended this “diet” cat food. Despite being severely overweight, Jack is really picky about his cat food. I ordered this cat food, which yes, is on the expensive side, but Jack loves it! I also have his brother, Mac (20 lbs), who is now on this food and he loves it too! Both boys are eating less as this food seems to leave them satisfied longer. After a month, Jack has lost 1.4 lbs so we are headed in the right direction! I’m happy my vet recommended this food. A little expensive, but worth it!

My boy Shadow loves this prescription dry food. It helps to keep his weight in check. This, partnered with the Purina Pro Plan OM canned food, has been great for his urinary health and keeping him from developing crystals in his urine. Many years ago he did have an episode of crystals, which was very scary. But thankfully he hasn't had any issues ever since our vet prescribed this wonderful dry food/canned food combination.

My little chunker has a massive appetite. When I tried to moderate her portions smaller than even normal to lose a little weight...she was so mad lol. This food

My little chunker has a massive appetite. When I tried to moderate her portions smaller than even normal to lose a little weight...she was so mad lol. This food allows her to eat and be full and she's actually lost three lbs and maintained it after being on this food for about three years now. SHE is definitely a picky girl too. So the flavor has to be good for her to eat it lol

My cat has not been on this food that long, but he seems to like the taste. His hunger seems to be satisfied with this food. I’ll be weighing him in the next week just to see if he’s dropping weight. That’s the most important thing right now. I guess we will see in time.

My Chubs like dry diet, not so much wet

I got him at almost 23 lbs, so big cat no matter what but needs to slim down. He loves to eat! So trying to cut down where I can diet dry and not a lot and as he doesn’t like diet wet, give him that in morning when he’s starved and fancy feast late afternoon. He’s adjusting to that menu somewhat. He doesn’t get lot of exercise in winter but summer he roams around big house and property outside. Can’t change six yrs of eating habits overnight but step by step. I give him protein not gravy food to fill him up. Hopefully by summer a few lbs will be missing.

I’m a longtime Chewy “family” member. For many years with my prior furry children and now with my newest addition s Giorgio and Andrea. Both rescues and adopted from Greater New Haven Cat Project. Giorgio is on special food as were my prior cats.Murphy and Tessa who were with me 18 + years each! I feel like the Chewy family cares about all of us pet parents as well as our sweet family members with fur . When I call to order more food the customer service reps re helpful ., personable and friendly.
