Wow, thank you for taking the time to let us know!!
Get him something like Tomlyn's Nutra-cal for Cats. It's a high calorie gel that you can dab in his mouth or, if he'll let you, rub on his gums. You can also put it on his paws and he'll ingest it by licking it off. There are many similar products on the market with different flavors so you may have to try a couple before you find the one he'll eat. They're available at any pet store.Does anyone have suggestions for high calorie things to give him? He seems to be eating more, and I'd like to take advantage of it to try to get his weight back up a bit.
You are awesome, bless your heart for coming back to this thread, and THANK YOU for loving black cats, and opening your heart and home to anotherHis name is Sommerfeld, and he's definitely taken the "crazy black cat" torch from Heisenberg and run with it!
