Pumpkin is almost 4 months old and I find wet kitten food is very limited in stores. Can I start mixing adult wet food into his kittie food? Im thinking he isnt getting enough calories. I do leave out dry food out through the day.
I start switching my kittens over to adult food by 4-5 months old, depending on the build of the cat. My rex kittens (who only get 5-7 lbs when grown, were on adult foods by 4 months old. Charlie (he's a solid 12 lbs now - full grown) was on adult foods by 5 months old.
If your kitten is in good health, I see no reason that you can't start him on adult canned foods. Is the dry food kitten food and what kind?
I wouldn't try to switch to dry-- just keep it out if he wants it but still mostly feed wet.
My kitten is 5 months and eats mostly adult wet food-- the options for kitten wet food is limited and I've only found them in the 3 oz size-- that would cost me over $3/day to feed him Wellness in the small can size.
