Sounds like an excellent plan. You are a great kitten tender, even if you were drafted and didn’t sign up to enter the service.
Funny story about bottle kittens. I belonged to a cat chat group once, and one of the members found two little kittens, definitely abandoned, not doing well. She asked for advice and got the usual notes about KMR, stimulating them, etc. Best wishes for these poor little things. She settled down to bottle feeding, and they perked up, grew, and thrived. She started offering cat food at appropriate stages, etc. All doing well.
SIX MONTHS LATER, she happened to ask the group, as she posted a picture of her healthy and frisky half-grown cats, “By the way, when can I stop bottle feeding them?”
She was new to kittens, and in all of the advice, nobody had ever said stop giving the bottle when they were eating other food well enough. Her only previous experience was with human kittens, who still are on milk at six months.
After everybody had a good laugh and the facts of cat ages were explained to her, she said, “But they still took the bottle and even asked for it!” I’ll bet they did. Feline con artists!
